Errata

Last week a typo slipped by our proofers. Command+M is not open a new document but that command is Command+N. Sorry about that. To make up for it here are a couple more keyboard combinations you might find handy:

Command-Option-Esc – If an app stops responding, you might need to force it to quit. You can do that with a right click on the app icon in the dock, but it’s even easier if you hit this keyboard shortcut. This will bring up the Force Quit dialog, which you can then use to make that non-responsive app quit. You might need to Command-Tab you way out of an active frozen app first, though, or use Command+Shift+Option+Esc to quit the currently active app.

Command-Option-P and R – Here’s one that might challenge your fingers dexterity. Fortunately, you will hardly ever have to use it but it is used to reset your non-volatile random access memory (NVRAM). Information stored in NVRAM can include speaker volume, screen resolution, start-up disk selection and recent kernel panic information. If you are asked to reset your P-Ram or NVRAM here’s how you do it.

1) Shut down your Mac
2) Turn on your Mac
3) Immediately after you hear the start up sound, hold down the command, option, P and R keys
4) Hold those keys down until you hear the start up sound again and then release them.
