What are ways to reduce mode errors while learning vim?

Question

I frequently make mode errors while using vim, i.e. I'll start typing text while in Normal mode, or start typing commands while in Insert mode. I understand this goes away with time as vim's quirks seep into your bones, but are there any ways to speed the process?

Answer 1

I use these autocmd's to highlight the entire line containing the cursor while in insert mode, and not while in normal mode:

if v:version >= 700
  autocmd InsertEnter * set cursorline
  autocmd InsertLeave * set nocursorline
endif

This provides a little bit more visual feedback about the mode.

Answer 2

If you haven't done so already you can display the current mode by using :set showmode. That'll display -- INSERT -- in the status bar when in insert mode.
