Tip: access defenses with a single key stroke

from unknown author, found in a newsgroup years ago

Sometimes you need a defensive weapon at your fingertips. Normally, you would have to select the item and then use it by hitting your defend key. With a text editor, you can make a couple of changes to your configs that will make a defensive weapon fire at the stroke of a key. First, open the user.cfg in your Base folder. This file contains any aliases you want to create. Let's say you want to create a key that activates the Tome of Power. Enter this into your config: alias +tome "use powerup;wait;+defend" alias -tome "-defend" Save and close your config file. Now, start your game. In the console, type: bind [key] +tome [key] can be anything that isn't already bound to another action. In the Options Menu, save your config. Now, in a game, you should be able to hit [key] and have your Tome instantly activated.
