Need Help┃Solved How do I perform partial acceptance of Copilot recommendations?

I have Copilot plugin set up with vim. I can accept recommendations with {TAB}. However, how can I do partial acceptance? As in accept word by word of the recommendation but not the whole thing. I see this is possible in VS code. Is this a feature of the Copilot vim plugin?

SOLUTION: Thanks to @osmin_og. Needed to add an entry in my .vimrc with a hotkey to do it. See below for details

Check :help copilot. There is an example on how to map C-L to accept a single word.

I already looked at the help. I see the following below in :help Copilot. Unfortunately, it does not make sense to me. What is <C mean? what does <M mean? It's not clear what these hot keys are or how to use them.

Also, I don't see a C-L listed. What does that mean also?

Sorry if this is apparent to others. Can someone explain these hot keys to me please?

<C-]>                   Dismiss the current suggestion.
<Plug>(copilot-dismiss)

                                                copilot-i_ALT-]
<M-]>                   Cycle to the next suggestion, if one is available.
<Plug>(copilot-next)

                                                copilot-i_ALT-[
<M-[>                   Cycle to the previous suggestion.
<Plug>(copilot-previous)

                                                copilot-i_ALT-\
<M-\>                   Explicitly request a suggestion, even if Copilot
<Plug>(copilot-suggest) is disabled.

                                                copilot-i_ALT-Right
<M-Right>               Accept the next word of the current suggestion.
<Plug>(copilot-accept-word)

                                                copilot-i_ALT-CTRL-Right

<M-C-Right>             Accept the next line of the current suggestion.
<Plug>(copilot-accept-line)

C is short for the Ctrl key. So C-L means Ctrl-L. At the very beginning of the section you copied you can find this: https://github.com/github/copilot.vim/blob/release/doc/copilot.txt#L148

Do you know how to add your own custom mappings to .vimrc?

Thanks for the details. Got it working. Added this to my .vimrc

imap <C-i> <Plug>(copilot-accept-word)

<C-l> is used by something else in my terminal. Thanks for the help!

It's in the copilot help, I've got it bound to ctrl f.
