Vim tip: Jump to a tag definition

I admit it, hitting control enter to jump to a definition is a very useful feature of fancy GUIs. Fortunately, it's not exclusive to fancy GUIs, apparently it's been available using ctags too for a little while (if you consider the last 20 or 30 years to be little, that is).

Just add this magic spell to your .vimrc; next time you open a file in a project with a tags file generated just press ctrl-enter with your cursor over the definition you wish to find:

map <C-CR> :tab split<CR>:exec("tag ".expand("<cword>"))<CR>
