Back in the 1980s there was an MS-DOS text editor called B.R.I.E.F. (Basic Reconfigurable Interactive Editing Facility — published by UnderWare). A behavior of that editor was when the home key was pressed once, the cursor would go to the beginning of the line it as on. Pressing it a second time (without any intervening key press) would take the cursor to the top of the screen, and pressing it a third time would take the cursor to the beginning of the file. Similar behavior existed for the end button.
Would it be possible to mirror this behavior in ST, and if so, how?
