default "Home" should be changed.
Pause is already taken as being a force pause (freeze).

But it doesn't actually work, it just lock up dosemu in a non-TSC mode unless the attached patch is applied.

One problem is that you can define just about any keycombo in some of these window managers, so there is nothing that works everywhere;

Well, there are either the combos that are always reserved by some WMs, and those can and should be avoided.

Quoted 1 line

however some combinations are used more often than others.

User-defined combos is not something we have to care about, that was not what I mean.

ctrl+alt+scroll_lock might be something that makes sense though, since you're locking the mouse.

The only disadvantage of it is that it switches a scroll-lock led:)

For KDE I have ctrl+alt+esc (kill), ctrl+alt+del (logout).

And you'll probably never know what other combos it already reserved without you even asking it about:) I think dosemu can avoid using those.
