I happened to find that we may open 'Terminal windows' in Vim and am happy to stop using terminal app. (It's available in v8 and v9)

However, when I have a typing mistake, pressing Delete key does not go backward and rub it out. Instead, it produces a strange letter 'ÿ'.

The only way I can fix such mistakes is pressing Ctrl-H (but this is tedious).

I cannot find documentation addressing this issue.

I tried to remap but both failed:

  :tmap <ÿ> <c-h>

  :tmap <del> <c-h>

Any suggestion?

  • Thank @Rich for improving my wording. And the nice-looking way denoting a key is worth learning! Oct 6, 2022 at 9:31
  • You're welcome. I only edited it because your key presses <Delete> were invisible due to the way this site formats things. If you don't want to use the <kbd> notation, you need to surround things like that with backticks: `

  • @Rich Thank you very much for your hint and suggestion! Now I learned the <kbd> markup - it's wonderful. The backticks used to mark a CODE piece up is also universally useful. (I used to write articles in Facebook. But since 10 years ago FB removed its limited markup ability (undocumented), I have not been aware that markup writing is so much well supported in other worlds!) Oct 10, 2022 at 4:52
  • You're welcome! There's loads more details about the supported markup available here.

I've just got the answer from a colleague. The following mapping works:

:tmap <BS> <c-h>
  • Are you perhaps typing on a laptop, or other small keyboard? Generally these don't actually have a Delete key: the key you were likely pressing is called Backspace, which would explain why mapping <del> didn't work but <bs> does.

  • Both my desktop and laptop were equipped with small keyboard. As far as I know, all Mac's keyboards have only <del> key and no <bs> key. (It's why I marked 'MacVim' at the title - it's a Vim port for Mac platform.) I have been working in Linux for 20 years. We used to buy desktops or laptops made for Windows. We always have the <bs> key above the <enter> key. There is also <del> somewhere else. Two years ago, I changed to adopt Mac as my working platform for some reason. I had hard time for 1 year to adapt myself to Mac - quite a lot was about the differences in keyboard. Oct 10, 2022 at 3:34
  • Looks like on a US keyboard, the key is labelled "delete", but it still functions as a backspace. To get <del> functionality you have to hold down fn while you press it. Try picking any of the other keyboards in the dropdown on the linked page: different label, same key.
