When you want to jump to a definition of a variable, what do you do? Use C-] or gd?
C-] finds only global variables (and functions; ctags extracts only global objects).
On the other hand, gd detects only local variables.
I think it's a bit complicated to choose between them. So I wrote this function:
function! GoDefinition()
let l:pos = getpos('.')
normal! gd
if getpos('.') == l:pos
execute 'tag' expand('<cword>')
endif
endfunction
nnoremap <C-]> :<C-U>call GoDefinition()<CR>
This function first does gd to try to find a local definition of a variable under the cursor, and if it failed then probably the variable is a global variable, so it tries :tag.
This way, you can jump to the definition of both local and global variables with the same key.
