For those of you who use MC and use Girder and are operating on a laptop. I have found a way to Hide/Show MC with a hotkey.
Step by step, this is pretty simple.
Step 1.
Create two new commands. Label one "MC Show" and the other "MC Hide" (or whatever creative names you wish)
Step 2.
On "MC Show" go to your O.S. action tab and choose "Execute" from your first drop down box.
Then either type or browse to the location of your Media Center.exe file.
Leave "Step Size" and "Startup Options" alone.
Right click on the 'MC Show" command in the tree and click "State Settings"
On "State Count" enter 2.
On "Begin State" enter 2.
check the "Execute on all states except 1" box.
Step 3.
On "MC Hide" go to your "Window" action tab and click the "Target" button.
In the "Target" window in the upper left corner is a little target icon. Im assuming if you use Girder, you know how to use the "Target" window by now.
Target the MC Titlebar. Then clear the childclass checkbox at the bottom of the "Target" window. Click "OK"
In the dropdown box, choose "Hide"
Right click on the "MC Hide" command in the tree and click "State Settings"
On "State Count" enter 2.
On "Begin State" enter 1.
leave the "Execute on all state except 1" box unchecked.
Step 4.
Set the same keyboard (or button) even for both commands.
And you're done.
This is for those of you who like to use the "Minimize to Tray" option. Otherwise, the process it slightly different.
If it doesnt work, then either my instructions are subpar, or you've done something wrong.
