On a PC, F2 starts the edit mode. On a Mac it cuts the content of the active cell. Countrol+U starts the edit mode on a Mac. It is possible to adjust the Mac keys to be the same as they are on a PC. See the related link below.
The Mac does not have a DOS mode to turn off. It does have a command line mode called 'Single User Mode' where UNIX commands can be executed. Get into SUM by holding Command S at startup. To go back to the Mac OS X interface, type 'reboot' and press the Return key. If you are having trouble with something you can also start up in 'SAFE' mode by holding down the S key during start up. Another handy key on start up is the shift key. You will start up with minimal system mode. And last, switch to a different hard drive to use as the start up drive by holding the option key at start up. Drives with bootable systems will be presented on screen. Tab to the one you want and press return.
$29.00 from Apple.com for a single user license, and $49.00 for a family pack (5 user license).
There is no DOS mode to get in to in Mac OS X and so there is nothing to get out of.
User accounts can be set up in the Accounts section of System preferences.
There are many types of single user operating systems available today; they encompass the systems found on mobile phones and personal computers. Examples of popular single user, multitasking operating systems, for example, include Windows, Linux, and Mac OS X.
It depends. If you have a mac, you could probably find it in the prefrences, although I am not sure about it for PCs, sorry.
