Enable/disable markers with shortcut.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Select node.
2. Click ctrl+1 one time.
3. Click ctrl+1 second time.

What is the expected output? What do you see instead?
I expect the following behaviour:
1. Xmind sets priority 1 marker on the node after first click.
2. Xmind removes priority 1 marker from the selected node after second 
click.

What version of the product are you using? On what operating system?
Xmind 3.0.3 on Linux and Windows
