By default the newer VMs implement the "traditional" Unix VM
behaviour:
Squeak X11
------ ---
shift Shift ^ Lock
ctrl Control
command Mod1
option Mod1 & Control
For keyboards that have more than one modifier key (Apple, Sun, etc.)
a more Macintosh Squeak-like behaviour is possible by specifying which
modifier keys should map to Option and Command, either on the command
line or by setting the corresponding environment variables:
Key X11 modifier VM option Environment
--- ----------- --------- -----------
Option mod<n> -optmod n export SQUEAK_OPTMOD=n
Command mod<n> -cmdmod n export SQUEAK_CMDMOD=n
Examples:
Apple keyboard, GNU/Linux, XFree86 4.0: -cmdmod 1 -optmod 2
Apple keyboard, NetBSD, XFree86 4.2: -cmdmod 2 -optmod 1
(these map "Option" to Option [duh] and "Apple" to Command)
Sun keyboard, Solaris: -cmdmod 4 -optmod 1
(this maps "Alt" to Option and "<>" [Meta] to Command)
If you don't know which modifiers are bound to which keys, then:
executing `xmodmap -pm' will print the keycodes and keysyms
associated with each modifier;
running`xev' and hitting modifier keys will generate KeyRelease
events in which the "state" field has bit N+2 set to 1 for mod<N>
(bit 0 is the least significant); i.e: state=0x8 corresponds to
mod1 (N = 1, N+2 = 3, 1<<3 = 8), state=0x40 is mod4, and
state=0x48 means both mod1 and mod4 are active simultaneously.
With a properly mapped Command key the pointer buttons and keyboard
shortcuts should work as follows (Option is generally ignored by the
image and is not considered below):
Pointer mappings:
Button1 (red) -> select (world menu on background)
Button2 (yellow) -> window menu (personal menu on background)
Button3 (blue) -> morph halos
Button1 + Shift -> extend selection (find window menu on background)
Button2 + Shift -> window "more" menu (find window on background)
Button3 + Shift -> morph halos
Button1 + Ctrl -> window menu (personal menu on b/g) = acts like Button2
Button2 + Ctrl -> morph menu
Button3 + Ctrl -> morph menu
Button1 + Command -> morph halos = acts like Button3
Button2 + Command -> window menu (personal menu on b/g)
Button3 + Command -> morph halos
Button1 + Shift + Ctrl -> (topmost) morph menu
Button2 + Shift + Ctrl -> (topmost) morph menu
Button3 + Shift + Ctrl -> (bottommost) morph menu
Button1 + Shift + Command -> extend selection (find window on b/g)
Button2 + Shift + Command -> window "more" menu (find window on b/g)
Button3 + Shift + Command -> morph halos
Button1 + Ctrl + Command -> morph menu
Button2 + Ctrl + Command -> morph menu
Button3 + Ctrl + Command -> morph menu
Button1 + Shift + Ctrl + Command -> (topmost) morph menu
Button2 + Shift + Ctrl + Command -> (topmost) morph menu
Button3 + Shift + Ctrl + Command -> (topmost) morph menu
Keyboard mappings (with reference to "World Menu -> help... ->
command-key help"):
key -> lowercase key
key + Shift -> uppercase key
key + Ctrl -> uppercase command key
key + Command -> lowercase command key
key + Shift + Ctrl -> uppercase command key
key + Shift + Command -> uppercase command key
key + Ctrl + Command -> uppercase command key
key + Shift + Ctrl + Command -> uppercase command key
(kilometrage with the others [delimiters, styles, kerning, etc.]
will vary according to whether particular symbols are shifted or
unshifted on a given keyboard.)
