With practice, keyboard shortcuts become faster than menu selection - A crossover interaction.pdf

Interesting learnings from these studies:

  1. Keyboard shortcuts are extremely beneficial for performance, but take some time to get used to.
    1. In the range of saving from .659s to 1.484s per use depending whether the user defaults to icons or menus. We could take an unweighted average of the two and say 1.07s saved for every shortcut, which could easily turn out to be several seconds every minute.
    2. Example: if the average person processing messages uses 6 hotkeys per minute, they’re saving 6 seconds/60 seconds, or about a 10% productivity gain in processing information. Most studies show a gain of anywhere from 10% to 50%, depending on the task being done. How would we value that?
    3. Let’s say your average employee spends 33.6 hrs (see other doc for data) per month on communications. Let’s assume they use minimal hotkeys and save 10% of that time, noted above at 3.4hrs per month, at $100/hr, this tool is saving $340/mo in lost productivity.
    4. It’d be awesome if we could measure this and report it back to enterprise folks in the future. @Logan Randolph Imagine a report that says, “Over the last X months, your average employee learned to use X% more hotkeys and is now Y% more productive, saving you $Z”
  2. Graphical user interfaces are great for novices and for functionality that is infrequently used
    1. Action item:
  3. People don’t think their performance improves after learning hotkeys, even thought it does

Questions: When to trigger keyboard use recommendations?

The hint we have at the bottom left doesn’t work because it’s not tied into how dopamine loops work. There needs to be a reward for doing it with the hotkey next time or people will tune it out.

Studies have estimated that it takes between 25 and 40 repetitions of a specific two-key pair for execution times reach a stable asymptote — With Practice, Keyboard Shortcuts Become Faster Than Menu Selection: A Crossover Interaction

<aside> 🤔 Idea: give people points for use of keyboard shortcuts? Maybe have a gauge that counts up to 50 points, and each use of a particular keyboard shortcut gives them a point. When they hit 50 points, they get a badge.

50 uses is probably a safe bet based on the research.
