Customizing Mouse Buttons

Mouse buttons can be "remapped" in the same way as keys. The command is:

SET MOUSE BUTTON number key-modifiers event definition


Is the mouse button number 1, or 2. Or 3 if your mouse has 3 buttons. This denotes which button causes the event. Normally button 1 is the left button.

Tells which, if any, keys are held down during the mouse event. The possibilities are NONE, ALT, ALT-SHIFT, CTRL, CTRL-ALT, CTRL-SHIFT, CTRL-ALT-SHIFT, and SHIFT.

Specifies the type of mouse event. The possibilities are: CLICK, DOUBLE-CLICK, and DRAG.

Is the definition for this event.
Thus, for a 2-button mouse, there are 2 x 8 x 3 = 48 distinct actions that can be assigned, and 72 for a 3-button mouse.

The definition is just like a key definition: it can be a single character, a character string, a Kverb, or any combination. Kermit 95 has hundreds of Kverbs. The following Kverbs are specifically mouse-oriented, but you can also assign other Kverbs to mouse actions:

Marks and copies text to the Clipboard.

Marks and copies text to the Clipboard, discarding line terminators.

Copies from the clipboard into the current Kermit 95 screen.

Marks and copies text to the SET PRINTER device.

Marks and copies text to the host.

Marks and copies text to the host, discarding line terminators.

Transmit arrow-key sequences to move terminal cursor to mouse position.

Send URL under mouse cursor to Web browser.


This puts the "URL hot spot" function on Ctrl-Button 1 (this is the default assignment).

Puts "paste from Clipboard" on Button 3 Shift-Double-Click.

In addition to the built-in mouse functions, you can write your own Kermit macros for processing mouse events. Kermit 95 provides three Kermit variables \v(mousecurx), \v(mousecury), and \v(select) which can be used in a macro.

The following macro starts the browser on the result of a drag event:

  define myurl run start \m(browser) \v(select), if terminal-macro connect

This can then be assigned to a mouse event with

  SET MOUSE BUTTON Button 1 Alt Drag \kmyurl

The \v(mousecurx) and \v(mousecury) represent the position of the mouse click or the end of the drag event. This can be used with the \fscrnstr() function to read text from the screen at that location.

Use SHOW MOUSE to show the current mouse event assignments.
