I use vim as a pager with vimpager and a script to change between pager and full vim mode.

But pressing i, a, etc change the mode while paging, which I want to prevent from happening.

I tried map i <Nop> and it works, but then I cannot restore the original behaviour, when switching to full vim mode.

  • From the vimpager github page: "To use a different vimrc with vimpager, put your settings into a ~/.vimpagerrc or ~/.vim/vimpagerrc or a file pointed to by the VIMPAGER_RC environment variable." Does it work to put your map commands there ? Apr 3 '17 at 13:49
  • I haven't tried it yet. I put the map commands after HideCursorInLessMode() and RestoreCursor() in ~/.vimrc, which should work the same as the alternative rc files you mention.

For my configuration for using Vim as a MANPAGER, I set nomodifiable. With that, Vim doesn't allow me to enter an editing mode:

E21: Cannot make changes, 'modifiable' is off

This doesn't block visual mode, of course, which makes it all the more convenient.

  • Thanks, but I meant all modes. I have mouse enabled, so selecting text changes the mode. I wouldn't mind mapping the relevant key bindings to <Nop>, but I still couldn't figure out how to get the original behaviour back.

  • @1.61803 what do you mean by "switching to full Vim mode" here?

  • You can toggle vimpager's default less mode with ,v to what I called 'full vim mode', that is as if you opened a file with vim foobar.

  • I tried nomodifiable in the script I referenced above, but then I'm not able to restore the normal behaviour with modifiable (in the function RestoreCursor()). Vim documentation doesn't say much about this option neither. Could you check that up?
