I am using the Alt key very often and I do like the HUD and want to keep both.
This is my problem: I always use Alt+D in Chrome to access the URL bar and I'm doing this very fast, but then HUD annoyingly pops up.
When pressing ALT + Tab very fast the HUD won't pop up, but if pressing ALT + D just as fast the HUD will pop up.
Is there a way to make it work like when pressing Alt+Tab, but with Alt+D? or edit the timer for how long I have to press until it won't pop up?
There are several ways to go about this. Here are three options I can suggest you to try. It really depends on how you prefer to go about it for your system.
System Settings - Option 1
Change what key calls your HUD or completely disable it like so:

Program Driven - Option 2
Maybe try editing your global hotkeys with a program.
xbindkeys | With this option you'll have to know how to call capabilities though shell commands.
(Other suggestions? Leave a comment and I'll add it.)
Programming Driven - Option 3
Here is a answer on SO that you may find useful regardless of what you do. This is a good answer to review especially if you choose to do this on your own programmatically along with this: Q&A How can I programatically show/hide my app window with global shortcut key?.
There is no difference between alt-tab and alt-d behaviour.
I tested this numerous times on 14.04. The only tricky part is that you have to make sure to press and hold the alt first. So don't press d first. You can see that every time you open the HUD, you have typed a
d
somewhere.alt - tab works in the exact same way...
