This is it, the biggest tip.
Our IDEs have an incredible number of useful actions, with many bound to keyboard shortcuts. You often discover one and think "That would be so useful!" But you then realize: "I don't want to use my mouse and I'll never remember shortcut number 427."
Lots of shortcuts. Different shortcuts on different operating systems. Too much to remember!
There's a better way: Don't.
Instead, memorize one shortcut:
Find Action (
Shift-Cmd-A macOS). With your keyboard and one highly-remembered
shortcut, you get fast access to all actions.
Find Action pops up the
Find panel with tabs for
Start typing the name of the action you're looking for and the autocomplete filters out the choices. Grayed-out actions are not valid in the context. Results also show the keyboard shortcut when an action has one.
Or use speed typing by putting in the first few letters of each
word in the action. For
Find in Path,
fi pa makes it the first-listed
action in the results.
One last point:
Find Action also matches preferences, and some are
inline toggleable. Want to disable tabs without opening
Find Action and type
wi pl no for
Window | Editor Tabs | Tabs Placement: None preference.
