Vim : changing text between html tags
For working between tags replace the " with a t, as in cit. Or dit to delete between tags and remain in command mode.
As you may already know, you can do ci[, ci{, or ci( to work between matched square or curly brackets, or parentheses. These commands also work with the closing character, so you can do ci], ci}, or ci).
cit
Mnemonic: "Change Inner Tag" -- This obeys tag nesting, as well.
