mouse resource

From The x3270 Wiki
Type Default Option
Boolean true

If true, c3270 will accept mouse-control events on terminal emulators that support them. This allows a left mouse click to move the cursor. On terminal emulators like xterm and gnome-terminal, this means that the usual mouse selection actions, such as highlighting text for selection, must be performed with the Shift key pressed.

If false, mouse-control events will not be enabled.
