Cert Week – Function Keys

Many people wonder what the top row of buttons on a keyboard are all about.  These are the Function Keys.  These have origins in the earliest days of computers.

My experience with computers goes back to the early 1980’s on a time-shared mainframe accessed on 64K telco data circuits and dumb terminals.  This was before there were mice, and application menus were selected and opened using the Function keys  (F keys) , and then using the Tab key to tab through the selections, and hitting Enter to execute a menu selection.

In the early nineties, I was working on a very new IBM clone personal computer.  Still no mouse, and to make finding the menu items easier, applications such as WordPerfect came with a cutout template that fit over the F keys.  Some examples follow:


I found the following image of the F-key functions.  These keyboard shortcuts sit work, and some of them may become favorites of yours.
