I kinda do for how ubiquitous Vim keybindings are.
Yeah, that’s a great reason to stick with it. It’s unfortunate that nothing really has Kakoune bindings other than Kakoune.
I think preference is generally subjective.
Of course, I know preference is subjective. That’s why I didn’t say “it’s better” :P Could very well be that vim works better for you.
The big reason I like them more is the concept of selections. Basically instead of a cursor you have a set of selections with start and end position (which could be the same position for a normal cursor), instead of having the object to delete as a parameter. For example, to delete two words it’s ‘d2w’ in vim, while it’s ’2wd’ in Kakoune. And after you type the ‘2w’, the selection shows what you’re about to delete, because it’s a separate command. It’s more useful when you’re operating on larger blocks of text, of course, or chain multiple commands together to create the selection you want. Sure, you can use visual mode in vim but it feels like an afterthought in a lot of ways.
I’ve already mentioned it but you can also have multiple selections at the same time, which I don’t think vim really does (I could be wrong though). This makes bulk operations really easy since they work exactly the same as operations on a single selection. For example, if you want to prepend let’s say “foo” to the next 10 lines, in Kakoune it would be ‘9CIfoo<esc>’ where C creates a selection one line under the current one, and I works the same as in vim. I believe you’d have to use macros for that in vim, something like ‘qqIfoo<esc>jq9@q’.
Those two are I think the main reasons I like Kakoune.
Doesn’t that disrupt muscle memory?
I haven’t really had problems with it, at least. Maybe because I’ve used vim for a long time before Kakoune. TBH I also don’t really use vim a lot anymore except on one remote machine that isn’t mine.
