Option-click shouldn't do anything in Squeak; is it being used for
anything?
What do you notice is different?
There is a preference and a command line option that may be able to
change some of this behavior:
* the "swapMouseButtons" preference
* the -swapbtn command line switch (assuming you've gotten one of
Ian's recent VMs).
There is always this code in EventSensor that you could change if
nothing else works:
mapButtons: buttons modifiers: modifiers
"Map the buttons to yellow or blue based on the given modifiers.
If only the red button is pressed, then map
Ctrl-RedButton -> BlueButton.
Cmd-RedButton -> YellowButton.
"
(buttons = RedButtonBit)
ifFalse:[^buttons].
(modifiers allMask: CtrlKeyBit)
ifTrue:[^BlueButtonBit].
(modifiers allMask: CommandKeyBit)
ifTrue:[^YellowButtonBit].
^buttons
But there is also code elsewhere that looks for the control key being
pressed during a click that may pre-empt this in some cases.
That is, in Morph>>handleMouseDown: there is a test for the control
key being pressed; if it is, you get the meta-menu.
Does MVC work right?
You may also want to look at what you have those keys mapped to in X.
This mapping can be changed if necessary.
When you run "xev" you should see the key events for the Alt and Ctrl
keys look something like this:
KeyRelease event, serial 27, synthetic NO, window 0x3a00001,
root 0x39, subw 0x0, time 2085057432, (894,728), root:(898,753),
state 0x8, keycode 64 (keysym 0xffe9, Alt_L), same_screen YES,
XLookupString gives 0 characters: ""
KeyPress event, serial 27, synthetic NO, window 0x3a00001,
root 0x39, subw 0x0, time 2085066406, (894,728), root:(898,753),
state 0x0, keycode 37 (keysym 0xffe3, Control_L), same_screen YES,
XLookupString gives 0 characters: ""
