In Vim, when I'm in Insert mode and hit d, the cursor moves back one spot for a second, then jumps back to behind the letter just typed. This is quite distracting when typing texts.

It looks like Vim is expecting a command because unlike other keystrokes, the d appears in the bottom right corner of the screen for a second.

However, according to :help the d only triggers an action in Normal mode, where it means delete. Would anyone know what d does in Insert mode and whether it's possible to avoid this behavior, e.g. through remapping?

Sounds like you've got an insert mode mapping that begins with a d, and Vim is waiting to see if you're typing that mapping or something else. To see what the mapping is, and where it was set, try the command:

:verbose imap d
  • Thanks! Strangely, I get to see mappings that don't have a d in them at all: i deoplete#auto_complete([]) * : "<C-Y>" Last set from ~/.vimrc line 51 i deoplete#close_popup() * : "<Tab>"<Space> Last set from ~/.vimrc line 48 Jun 22, 2020 at 16:07
  • @TimothyRoes Those mappings do have a d in them! They are mappings for deoplete#... i.e. when you type deoplete#..., the bit after the * will be entered instead. You should take a look at lines 48 and 51 of your .vimrc, because it looks as though the mappings there are broken/missing their lhs (i.e. their triggers).

  • Thanks, that totally fixed it. The syntax was wrong. Deoplete :help was rather terse on this point, but referring to the general vim :helpI managed to understand :map-expr . Jun 23, 2020 at 7:18
