- Ctrl+=: Increase font size
- Ctrl+Dash: Decrease font size
Press Ctrl+= (that is, the Ctrl key held down, and then the = key) and the font size on the current page or e-mail will increase.
(A lot of people write this tip as Ctrl+Plus, because the mnemonic of the + key increasing the font size is easy to remember, but you don’t need the Shift key in there.)
Ctrl+Dash (that is, the – key, or minus — the key right next to the = key) will reduce the font size.
Each time you press the key, the font gets bigger or smaller. When you want to go back to normal, press Ctrl+0. (Thanks to Steve in the comments for that last one.)
(This is a little hard to write, given the terminology I’m using. I should refer to “Control with the Plus key” as Ctrl++ and “Control with the Dash key” as Ctrl+- but that looks really weird. Sorry if today’s tip is confusing!)
