Ale's method was using the system keyboard mapping to rebind to items in the menu. But in TextMate specifically, if you create a keybinding in the bundle editor, it will override the bindings in the menus, so you can use this method to override with a new action, or neuter a keybinding as shown above.
Unfortunately, what I actually did was rebind (in OS X in general, using KBE) ^j => move left one character. So it wasn't a bundle binding problem, but rather the fact that TM was using a binding I wanted to be more general. (In general, I bound ^j, ^k, ^l, , ^; to char left, line down, line up, char right.)
Also, you can type ñ with this sequence: Option-n, n
There's approximately 0% chance I'll remember that, but I do appreciate the info. Gawd, I wish I knew some languages other than English.
