Custom name for keybinds

[4164696f73]

I haven't found any way of achieving that, so hence I posted this suggestion.

When you assign multiple commands to one keybind (e.g. D -> d, D -> e etc, see screenshot), the command chain displays "[Multiple commands]", even if the key chains are different. Would be cool to be able to adjust that for our keys, for example like D = { d[Custom Name] = ["extend_line", "delete_selection" ..., so that we actually know what the command does, or if someone would use our config.

I don't really have a good implementation idea for it, but I think the most readable way would be adding a new section in the config where you specify the commands just like above, but instead of assigning commands, you assign names, for example:
[commands.rename]
D = { d = "Empty current line", e = "Kill to line end, yank", s = "Kill to line start, yank" }
