Map <CR> to checkout the branch under cursor

[mcepl]

It seems to me that the most intuitive action one needs to do with the Merginal is to switch branches. Is it just my stupidity that I cannot find it in documentation, or CR is really not mapped to call b:merginal.checkoutBranch()<CR>? Shouldn't it be so?

<Cr> is not mapped to anything in the Merginal buffer. I can see your point about it being the most intuitive, but I'm kind of worried about mapping <Cr> to something that modifies the files on the disk.

In the files diff buffers <Cr> is mapped to open the file under the cursor, but that action is easily reversible with <C-o>. Checking out a branch is not trivially reversible, so I find it too dangerous a command to be mapped to <Cr>.

Well, git checkout <branch> (without -f) fails if any changes in the working tree (or even index) would be destroyed by it. I guess, that command was meant to be safe for this.

@mcepl I wanted the same feature. I forked vim-merginal, added support for filetypes, and then mapped Enter to checkout a branch when in a merginal buffer.
