Review request for kwin, Plasma and Hans Chen.


Repository: kwin


Description
-------

On popular demand!

This change tracks how modifiers are used and detects a modifier only
key press/release. That is:
* no other key is pressed when the modifier gets pressed
* no other key gets pressed before the modifier gets released

If such a press/release is detected, we call a configurable dbus call.
The possible shortcuts can be configured in kwinrc, group
"ModifierOnlyShortcuts". The following keys are supported:
* Shift
* Control
* Alt
* Meta

As value it takes a QStringList (comma seperated string) with
service,path,interface,method,additionalargs

E.g. to invoke Desktop Grid effect on Meta key:

[ModifierOnlyShortcuts]
Meta=org.kde.kglobalaccel,/component/kwin/,org.kde.kglobalaccel.Component,invokeShortcut,ShowDesktopGrid

I do not intend to add a config interface for it. Let's keep it a hidden
way.
