I was hunting around the various menu’s of Terminal a bit earlier today. I was a bit bored and I had a look it see what they could offer. Anyway I came across the following shortcut in the View menu and I was a bit perplexed at what key it could be. I tried both up and right at the same time, but nothing did seem to work.
In the words of Homer Simpson:
“To start, press the diagonal key.” Where’s the “Diagonal” key?! I see “Kuh-tor-ull”, “Esc”, and “Pig-Up”, but I don’t see the “Diagonal” key! Woah, all this computer hacking is making me thirsty, I think I’ll order a tab… (Presses tab key) Ooh, too late for that now, the computer’s starting!
Anyway there is a solution to find any keyshort cut on your computer. It is to use the keyboard viewer. To access the keyboard viewer open System Preferences > International > Input Menu. At the top of the list select Keyboard Viewer a new icon should appear in your menu bar on the right hand side. Click on this and selection Show Keyboard Viewer.
The keyboard viewer will show you every single key and key modifier you have available to you. At this point to find the key you want you have to go through the modifiers. Alt, Command, Control and Function. Every time you press theses and a combination of these a different symbol will appear on your viewer. After a little bit of trial and error you can find the key you want.
To answer the original question in the title. The diagonal key is both the function and the left or right arrow. The up and down arrows are used to move up or down a whole page.
A simple little step using the keyboard viewer would have saved me about 10 minutes of frustration and Google searching.
