In my decades of leading software teams, one thing I did not do is ask
"What editor do you use?", even in employment interviews. In my
experience, a programmer is most productive using the editor with which
he's most proficient. End of story.

On the three occasions I've had to extract a marsupial possum from our
chimney (they're like a cat on steroids), I've armed myself with thick
leather gloves and grim determination. For vim, a cheat-sheet suffices,
and :help xxxx" or google do explain.

That's an xterm error, as the arrows simply produce motion even in
Insert-mode, if that's properly set up.

But Vim's Insert-mode/Normal-mode modality still requires user
awareness, either through memory or looking at the status line, with a
"set showmode" in ~/.vimrc - unless you also add something like:

" These days I expect to be out of insert mode, after a vertical move:
inoremap <Up> ^[<Up>
inoremap <Down> ^[<Down>

(The ^[ is <Escape>, entered as <Control-V><Escape> in insert mode.)

Now the Insert-mode exit is automated, so long as you use the arrow keys
for moves. (If you use hjkl for speed, then you're not a novice, by
definition.) I've left <Left> and <Right>, so I stay in Insert-mode
while on the line. It works for me, but you could remap them too.

To avoid the need to glance to the bottom of the window to check mode, I
also add:

" Cursor Appearance and behaviour:
" (Insert_Mode == Green, Normal_Mode == Red)
if &term =~ "xterm"
   let &t_SI = "\<Esc>]12;yellow\x7"
   let &t_EI = "\<Esc>]12;green\x7"
endif

So the cursor itself is a reminder. (I haven't yet found a way to have
it make coffee though, so that I always have my eyes open.)

Even without integration in an editor, in *nix you can Control-Z out to
the command line, run make, and fg back in. I too would use whatever
editor my fingers remember.
