Continuing my internal series on keyboard short cuts,  have to recommend Ctrl+Z this week.

This is known as the "Undo" or "Oh, shit!" shortcut. That is because it undoes the last thing you did.

This is mostly used in word processing or other programs where you make stuff. It is great if you deleted a chunk of material on accident, moved something where you didn't want it to go, or had an image go wonky in editing.

In many programs, you can keep Ctrl+Zing until you run out of things to undo.

My colleagues and I were talking about how we often teach students about keyboard short cuts. We ended up in a discussion about where folks learn these. The obvious is Google, but most people learn them when someone sees them doing something with a mouse or manually, and jumps in with a keyboard short cut suggestion.

Just the other day, I did this. A student was clicking back and forth between programs on their computer. I let them know about Alt+Tab which lets you do that without a mouse. It's a minor change, but once you do it, you'll use it forever. 

I love Alt+Tab because it lets me have our reference chat open in one browser window and my other work in another. When I chat pings, I can quickly switch to answer without losing what I was working on.

When someone asks me a reference question, I always follow-up by asking them "why?"

​Why are you interested in this? Why do you need this? How are you going to use what we find? 

This is not out of curiosity or concern. I ask "Why" because it helps me determine what kind of information you need. Why lets me know format. Why lets me know content level. Why lets me know depth and detail. Why lets me know timeline.

I ask why in many ways and more than once. Then I use what I learn to help you find what you need.

Anytime you look for something, ask yourself "why?" It can help focus your work saving you both time and stress.

Keywords are important terms, concepts, or phrases you can use to help you search for  information. If your keywords aren’t right, you’ll have trouble finding what what you need.

When developing keywords, try the following:

• Underline Your Thesis: Look at your thesis or research statement and underline the most important words, ideas, and topics. These are your starter keywords. 
• Find Synonyms: Don’t get tunnel vision and only focus on the keywords in your thesis. Look for synonyms to those words. You can use a website like Thesaurus.com or a print thesaurus to help you find related terms. The reason you should look for synonyms is that the keywords you use might not be the keywords an author/creator uses even though you're both looking at the same thing.
• Expand Your Idea: Expand your topic a bit. What are the overarching ideas or topics that cover your topic? If you want to research gentrification in a local neighborhood, it’s worth looking for articles on gentrification in a specific city or gentrification trends overall. 
• Narrow Your Idea: Find an example you can use. If you’re researching social media, pick a specific platform like Twitter.
• Specific Examples: If you are writing about a general idea, it can be useful to include specific examples of that idea as keywords. For instance, if you're looking at Black authors, you could include Octavia E. Butler as a specific example.
• Related Ideas: You can also look for keywords that are related to but not directly about your topic. If you’re looking up healthy eating techniques, you might want to find articles on other healthy habits like exercise or sleep. Information you need may be included in an article on another topic.

A great way to make sure you're getting all the search results you need is to use the Boolean operator "OR." 

When you connect your keywords with OR - for example, by typing "climate change" OR "global warming" into the search box - your search results will contain articles that contain at least one of the keywords you entered.

This is a helpful approach when you are searching for concepts that have many synonyms or can be expressed in several different ways. 

It's an inclusive search technique that basically says, "I want it all!"

One of my favorite search skills is eliminating things from the results list. There are so many words and phrases that overlap or are interdisciplinary, it can be hard to weed through all the results. 

Enter the Boolean operator NOT.

You can use NOT to exclude particular words or phrases from your research results. For example, if you are interested in finding resources about the effects of climate change other than sea-level rise, you can type ["climate change" NOT "sea-level"] into the search box.

In some tools you use a minus sign (-) instead of NOT, but the function is the same.

Some databases also offer filters where you can use checkboxes to exclude certain terms, subjects, or resource formats.

All of these function to help you reduce the number of results to find more targeted and relevant resources.

One of the best parts of reference desk work is that any life experience can come into play.

For example, I helped a visitor today by using my personal parenting experience.

This parent was on campus with two children. The first was attending a camp on campus. The second just needed to be occupied for a few hours. I recommended a trip to the zoo or a playground up the road. I was well versed in both because I frequent them with my own child. She asked about the playground and I was able to share my experience as well as directions.

When you share information that you know well, you make a stronger case. You can share more details and insights which gives a fuller picture.

One of the most common requests we see at the reference desk is "I need information about X." 

That "X" is generally a broad and undefined topic that can be tackled in numerous ways. This is where brainstorming comes into play.

When brainstorming you want to consider:​

• The who, what, where, when, why, and how of the general topic​
• ​How would you like to answer your question?
• What kind of information exists on this topic?
• What do trends do you see?​
• What gaps can you identify?​
• What questions do you have?
• What do you find interesting?​

I like to recommend that students keep a list of information as they think through these questions. Then, they can develop a mind map to help connect ideas, themes, topics, and examples. Using brainstorming can make it easier to develop a strong research question and find keywords for searching.

Sometimes spelling can be a real hassle when it comes to doing research. Between the differences of British and American English and the various endings we give words, it's a pain to try to cover everything.

That's why I love the Wildcard character of Boolean search. Simply put an asterisk (*) on your keyword and save yourself some time.

The asterisk allows you to search for a root word and all its different endings. For instance, "educat*" will search for educate, educates, educated, education, educating, educational, and educator.

You can also use a wildcard within the word; for example, you can use "wom*n" to search for woman or women.

Note, however, that some unrelated words have the same root. You may try "polic*" to search for policy or policies, but it will also search for police.
​
Most places use an asterisk (*) as the wildcard but some use a question mark (?). You can usually find out which character to use on the search tool's Help page.

Sometimes the best tips are the simplest.

One of my favorite shortcuts is Ctrl+F. This is the keyboard short cut for the Find command.

Simple hit the "Ctrl" key and "F" key at the same time to open up a small search box in your document, webpage, or whatever is on the screen. Then, you can put in the word you are looking for. You have to type in the exact thing you want (this won't autocorrect or understand what you want like Google).

This is really helpful when you need to search long pages of text to see if they have what you need. It's also great for when you just know something is in a document but can't remember where. 

I use Ctrl+F a lot when I am working with students to show them how to quickly "read" an academic article to determine if it's a source that will work for them. I also like how, depending on the program you're in, Ctrl+F will also show you how many times your search appears in the page. That's a great way to know the density and importance of a topic in whatever you're looking at.
