You can use my project https://github.com/fatih/subvim
For cmd+r
you can directly jump to any definition on the fly. No need to genarete tags or whatever. Currently any language supported by ctags can use this feature. I've also add languages like Go, Coffeescript, Objective-C,etc... It means just fire it up.
Also it has Sublime-like features backed in (means no plugins necessary). Thus you can use the following shortcuts:
cmd + p
-> go to anything
cmd + t
-> go to file
cmd + r
-> go to symbol
cmd + k
-> show side bar
cmd + /
-> toggle comment
cmd + [
-> indent
cmd + ]
-> unindent
cmd + <number>
-> jump to tab 1, tab 2, ...
cmd + alt + left
-> move to next tab
cmd + alt + right
-> move to previos tab
cmd + z
-> undo
cmd + shift + z
-> redo
cmd + s
-> save file
cmd + w
-> close
cmd + f
-> search
Also autocompletion, restoring latest session, automatic bracket closing and many minor changes make it really a joy to use.
