I found that the HUD and Ubuntu Menu (or "Dash") keys (ALT & SUPER or WIN_KEY) are very annoying for any application... so the way I fixed this was changed the keybinds to something a bit more appropriate for me. This might help you, so I'm going to outline how I did this:
First you need to install a program to manage Unity and other Compiz settings called "CompizConfig Settings Manager:
sudo apt-get install compizconfig-settings-manager
- Run CompizConfig Setting Manager, by looking for it in the "Dash"
(Ubuntu Main Menu/Start Menu/Whatever you like to call it).
- Under the "Desktop" section, look for "Ubuntu Unity Plugin", and click on it.
- Change the values you need. The button you need to press is next to the titles I give below:
- "Key to show the HUD" - I disabled the HUD, but you could use: "CTRL + ALT" instead.
- "Key to show the Launcher" - I changed this to "CTRL + Super", however it shows "[Control][Primary][Super]" - this is fine, since CTRL+Super still works as it should. Pick whatever you feel comfortable using.
- Click the "Back" key when your done. Please note changes above should change instantly.
The main reason I did this too, was because I like freeing up my Super key to be able to do other shortcuts. For example Super+T = Terminal, Super+g = Gedit, Super+c = Chrome, Super+PRINT_SCREEN = grab section of the screen (for taking screenshots). If you want to set something like this... then the section is called "General" and the button to press is "Commands". Please leave "Command Line 0" as blank, I noticed mine has a key binding of "Escape" - and wasn't sure if this was important for anything, so I started from "Command Line 1".
Hope this helps you.
