If you are new to Mac OS X, it can be frustrating to learn some of the hot-keys that you were used to on Windows. While there isn’t always an exact equivalent, there are a few shortcuts that are similar and will get you started.
In Windows Control-Alt-Delete will bring up the security window allowing you to change users and lock the computer, among other things. There are a few hot-keys on the Mac that can perform the same functions.
Control-Shift-Escape pulls up the task manage on Windows and the equivalent on the Mac is the Force Quit menu. You access that with Command-Option-Escape.
You can put a snapshot of screen into your clipboard on Windows with the Print Screen button. Mac offers several hot-keys for screen shots:
The cursor changes to show you which screen shot type you’ll be taking, and the shot it saved to your desktop.
There are many shortcuts you can use to open, edit, manage and close documents and files in Windows and Macintosh.
You can learn other Mac shortcuts by going to the System Preferences, then Keyboard in the Shortcuts tab. My favorite hot-keys are Command-Q to quit apps and Command-W to close windows.
