My Favorite Firefox Keystrokes

Ctrl + T
Opens a new tab, and places focus in the location bar. One tab and I�m in the built in Google Search box. Nice.
Alt + D
Goes to the location bar, highlights the current address so that I can copy it, paste over it, or just start typing.
Ctrl + Tab / Ctrl + Shift + Tab
Cycles through the open tabs either forward or backward (using shift)
Ctrl + H
Takes me to my home pages; currently AccessifyForum and my helpdesk software, each in their own tab.
Alt + S
Opens/closes Sage in my sidebar; it is a great little RSS/Atom reader for easy digestion of my favourite sites.
Ctrl + Numpad plus / Ctrl + Numpad minus
Update: also works with main keyboard plus and minus signs.
Scales text size up and down accordingly to adjust for microtype sites or for viewing at a distance while casually reading.
Ctrl + 0 �zero�
Recently discovered. Resets text size back to default. Ultimately convenient when switching back to testing/developing from casual reading. This only works with the main keyboard zero, not the one on the number pad.
Ctrl + Shift + E
With Chris Pederick�s Web Developer Extension, this takes me to Edit CSS mode, opening a sidebar containing all the CSS for the current page. Allows for live editing of CSS. Huge time saver for debugging CSS problems or for WYSIWYG CSS development.
Ctrl + Shift + V
Again, with Chris� toolbar, validates current page. Opens in a new tab.
Ctrl + U
View source. Must have.
Ctrl + Y
Opens download dialog box. Not used often, but handy when I need it.
