Re: keyboard shortcut problems



I have placed a couple of pictures of apple azerty keyboard online [1], to help those who may never have seen such keyboards. I also found a picture online of what I take to be a german keyboard [2].

As you can see there are two symbols on the "alt" key. I take the symbol below "alt" to be the symbol for the compose character key. I am not sure how this maps to xkeycaps. But it certainly seems to be different to what "alt" is used for in windows, which usually has a special key for character composition to called alt-gr to the left of the white space.

As I can remember unix allows you to set (using xkeycaps for example) control, alt, meta and hyper keys. It also allows one to distinguish between right and left versions of these keys.

It would be really handy to have a document explaining the mapping of these control, alt, meta and hyper keys to their windows and apple equivalents with explanations of their usual intended purpose for each purpose. Something like this would be sorely needed to help people write cross platform shortcuts.

I am myself already starting to get a better feel for the problem.

Hope this helps,

Henry Story

I read once more Henry’s message (just before hitting the reply button) and definitely, he is right, but his description apply to a Windows machine. Using Alt (instead of Option) make me feels that. Running Windows XP, the user press Alt were the Macintosh user press Command. Here is the lying :(.
I may be wrong, but when the software runs under Mac OS, the keyboard shortcuts must use Command instead of Alt (Mac OS says Option where Windows says Alt).

Actually, Control under windows is more equivalent to Command (aka Meta) in OSX, that is, as an accelerator key modifier. Java will handle this under the covers for you if you use Toolkit.getMenuShortcutKeyMask().


Alt in Java is used as a focus accelerator (meaning the alt-KEY combination moves focus somewhere) regardless of platform (native w32 apps sometime use this, most OSX apps don't).

which I suppose explains why Netbeans uses Alt-o for the "open source" command which should move me to another window...


In general, Alt under w32 is used for keyboard traversal rather than for accelerator keys, although there's nothing to stop it from being used as one.

I am not sure what keyboard traversal is.


X11-based systems (linux, un*x) used to use Alt as an accelerator, but most UIs now seem to follow w32 usage.

Perhaps for a future release it would be possible to provide alternate bindings so Alt is simply never used for binding actions; however doing that presents a couple of problems: 1. The alternate keybindings would need to be documented (as in, docs writers will strenuously object),

true, but there may just be no way around this.

and 2. There simply may not be enough keys to go around, sans one modifier key - at least not while producing vaguely intuitive shortcuts.

Others seem to suggest there are enough. Look forward to your response :-)
