161142 - Inconsistent (broken???) keyCodes for dash/subtract keys

Status: RESOLVED FIXED

(Core :: Widget: Win32, defect)

Description

[Robert Kieffer]

I'm seeing inconsistencies with how the dash ('-' on keyboard) and subtract ('-'
on number pad) keys work across platforms.  The following table lists the
event.keyCode values that I've been seeing on the various systems.

               dash   subtract
NS7PR1/Win2K   0x6D   0xE2
NS6.2/Win2K    0x6D   0xE2  
Moz1.1/Win2K   0x6D   0xE2
IE5.5/Win2K    0xBD   0xE2

NS7PR1/MacOSX  0x00   0x6D
NS6.2/MacOSX   0x00   0x6D
Moz1.1/MacOSX  0x00   0x6D
IE5.1/MacOSX   0xBD   0x6D

http://lxr.mozilla.org/mozilla/source/dom/public/idl/events/nsIDOMKeyEvent.idl
lists the keycodes for Mozilla, but only the code for
DOM_VK_SUBTRACT (0x6d) is listed there.

I'm not sure what the "right" values are, but I'm pretty sure that, if nothing
else, the zero value on MacOSX is wrong.

This should probably get assigned to someone has a valid email address and might
look at this sometime this millenium.

By the fix of bug 630810, now, keyCode value of printable keys are in standard location is computed from unshifted character. And if the unshifted character is '-', DOM_VK_HYPHEN_MINUS is used.
