MouseText

MouseText is a set of 32 graphical characters first implemented in the Apple IIc. They were then retrofitted to the Apple IIe forming part of the Enhanced IIe upgrade. A slightly revised version was then released with the Apple IIgs.

The MouseText characters replace a redundant set of Inverse UpperCase characters (@,A..Z,[,\,],^,_) in the Alternate character set.

How to access MouseText characters

In order to display MouseText characters a program must first select the Alternate character set, turn on Inverse video mode and then output an ASCII 27 character. To turn off MouseText the program should output an ASCII 24 character and the if required return the display to Normal video mode. For example, in Applesoft the following code fragment will display the MouseText Folder icon.
