First of all, Welcome to the Discussion forums!
As Kurt has cited, CommandOption+ShiftEject, will quit all open applications and shut down your iMac.
"on the menu the Force Quit shows three keys to press together"
A force quit is command + Option + Escape key combination. This will bring up a force quit pane that will allow you to select applications individually to force quit.
See: List of OS X keyboard shortcuts
A great Apple Knowledge Base article to bookmark when learning keyboard commands.
I would suggest that you use your installation cd/dvd to boot up and use it's Disk Utility from the Installer Menu in the top menu bar to Repair Disk. When you have force shut down your computer multiple times you could have corruption that should be repaired.
hope that proves helpful,
