nowadays, all the keyboards have a "windows" (or "apple") key.
on the other side most graphics programs (gimp, inkscape, scribus, ...) and some games use alt + mouse for some features.
for this reason, there should be an easy way to switch between the alt key and the windows key as a modifier for moving and resizing windows.
if possible, the default should be to use the windows key (almost only advanced users currently use the alt key to move the windows: they will find the new key or find how to switch back; beginners won't understand why the alt key does not work as it does on other setups).
thanks for caring
a.l.e
this is all controlled in the openbox configuration file. it doesn't exactly fit the scope of LXDE because it introduces a dependency. MAYBE the feature should be added to some kind of openbox plugin thing like LXAppearance has.
The syntax for the config file (usually in ~/.config/openbox/SESSIONNAME-rc.xml) is:
<context name="Frame">
<mousebind button="A-Left" action="Drag">
<action name="Move"/>
</mousebind>
</context>
To use the flag key instead you change A-Left to W (I think, haven't tested really...).
as i said, the goal is to have the alt key free for the applications.
if you don't want (or can't) provide a way to manage that key, please switch the default in the config file (i've tried it and it works!)
wmii -- despite being a window manager for geeks who should be able to modify a config file -- has the best solution i've seen: it asks on the first start which key you want to use.
lxde is a very good desktop environment for workshops and i'm not the only one using it to show graphics applications to new people and i'm installing in on old machines i give away for tests...
i will be documenting how to switch the keys by editing the config file, but for many people this is a bit too hard core.
