"Return the key translated via the translation table.
|
|
89
|
1161 |
Your application program should never depend on the values returned
|
|
|
1162 |
by this method, but instead use symbolic keys (such as #FindNext).
|
|
|
1163 |
Doing so allows easier reconfiguration by changing the translation map
|
|
|
1164 |
in the 'smalltalk.rc' or 'display.rc' startup files.
|
|
51
|
1165 |
|
|
|
1166 |
First, the modifier is prepended, making character X into
|
|
|
1167 |
AltX, CtrlX or CmdX (on most systems, no separate Cmd (or Meta)
|
|
|
1168 |
key exists; on those we always get AltX).
|
|
89
|
1169 |
If multiple modifiers are active, the symbol becoms the concatenation
|
|
|
1170 |
as in AltCtrlq (for control-alt-q). Shift will affect the last component,
|
|
|
1171 |
thus the above with shift becoms: AltCtrlQ instead.
|
|
|
1172 |
Some keyboards offer both Alt and Meta keys - on those, the first has a
|
|
|
1173 |
prefix of Alt, the second has Cmd as prefix. Keyboards with only an Alt
|
|
|
1174 |
key will will create prefix codes of Cmd for that.
|
|
|
1175 |
For symbolic keys (i.e.Tab, Backspace etc, shift is ignored).
|
|
51
|
1176 |
Then the result is used as a key into the translation keyboardMap
