An app could track which actions I take manually, in order to learn which shortcuts are most valuable to teach me.
Immediately after I manually take a frequent action, it could inform me of the shortcut. Perhaps I can then even undo the action and redo it using the shortcut, to build muscle memory.
Once I've mastered the shortcuts for my most frequent actions, the app could move on to teaching less-frequent ones... perhaps up to some threshold.
What I dislike about editors is that there's just no default shortcut set for a lot of actions I commonly use, and I have trouble coming up with new ones that aren't already in use.
If you know the name of the icon or component, you can begin typing it into the runner bar and place it instantly. No need to hunt through all your nested symbols. It also works wonders when needing to replace existing symbols.
