Customize comma leader?

[justmytwospence]

Is there any way to use another key instead of , as the Vmail leader key? Something like the spacebar would be much more comfortable for me personally.

Vmail maps the leader key to ,. So you can simply remap the leader key to something else. See :h leader.

I already have let mapleader="\<Space>" in my vimrc, but it is overridden by vmail. I can't seem to set it manually either. Does it need to go in an ftplugin file perhaps?

[notalex]

Yes. ftplugin should take precedence over vmail mappings. Also you would
need to check for a global variable g:loaded_vim. This will help you
avoid overwriting the leader key for non vmail windows. If you need help
with the exact script, let me know.

[notalex]

Sorry, you actually do not need that global variable. The mapping should be set in a ftplugin for vmailMessageList. This is the first buffer that is loaded.

Still no luck. This is the contents of my vmailMessageList.vim:

call clearmatches()
let mapleader="\<Space>"

Pressing space still toggles "fullscreen". Is there something else that needs to be unmapped from the spacebar?

[notalex]

Seems like I failed to understand mapleader correctly. As per :help mapleader,

Note that the value of "mapleader" is used at the moment the mapping is
defined. Changing "mapleader" after that has no effect for already defined
mappings.

So my proposed solution would not work. I will look for other alternatives.

Perhaps <LocalLeader>? I'm looking into it as well.

ever find a solution to this? it seems weird to me that vmail sets leader at all
