You can program mouse buttons to run commands from the command line by clicking the appropriate mouse button. You can only program commands to mouse clicks; not to clicking and holding down the mouse button.
EPIC supported a three button mouse on the workstation, and a two button mouse on the PC. The FPGA Editor supports only the left and right mouse buttons on the workstation. The following table includes some comparisons between EPIC and FPGA Editor mouse actions.
| Function | FPGA Editor on Workstation and PC | EPIC on Workstation | EPIC on PC |
|---|---|---|---|
| Zoom in | Control + Right Click | Middle Click | Right Click |
| Zoom out | Shift + Control + Right Click | Right Click | Shift + Right Click |
| Pan | Control + Right Drag | Right Drag | Right Drag |

| Display a context-sensitive popup menu for the selected window area or design object. Use the right mouse button to select a command from this menu. | Right Click | N/A | N/A |
To re-program mouse buttons, use the Alias command in the fpga_editor.ini or fpga_editor_user.ini file, as shown in the following lines from the default fpga_editor.ini file. For more information on the Alias command, see the “Alias” section of the “Command Line Syntax” chapter.
alias [LeftClick] "unselect -all; pick -order pin:etc"
alias [Control+LeftClick] "pick -order pin:etc"
The mouse aliases used in the default fpga_editor. ini file are shown in the following table. If you unalias a programmed mouse button, the FPGA Editor restores the default command to that button.
