Feat: Accept Copilot Suggestion Up To Character (Find Motion Support)

[Or1g3n]

Summary:
Requesting a feature to accept Copilot suggestions up to and including (f motion) or up to before (t motion) a specified character (i.e., leverage Vim’s f and t motions).

Example:
Given the suggestion:

The quick brown fox jumps over the lazy dog.

• Typing a key sequence like fj would accept and insert:

  The quick brown fox j
  

  (up to and including the first j in the suggestion).

• Typing a key sequence like tj would accept and insert:

  The quick brown fox 
  

  (up to but not including the first j in the suggestion).

Rationale:

• Provides granular acceptance of suggestions.
• Mimics familiar Vim motions for efficiency.

I just realized that find motions are only valid in normal mode which creates a challenge given copilot autocomplete is taking place in insert mode. It could be that C-f or C-t triggers the behavior, or to stay native vim, C-o already handles this situation where you temporarily exit insert mode to perform a normal mode motion. Another thought, if copilot has a way to expose suggested text, then other plugins like flash, leap, etc. could leverage this to get super granular methods of completing up to the exact character.

Not sure how feasible any of this is, just some thoughts. Ultimately if there is a savvy way to get more precise acceptance of suggestions then I don't really care what the method is. Appreciate anyone who has taken the time to read this request!
