I always have my IDE (phpStorm) in full screen mode (Yosemite).
I want my iTerm2 hotkey to slide my terminal window down over the IDE, so it doesn't open up a new space for the terminal window. As once the window slides back up it leaves me on an empty space, rather than going back to phpStorm.
This is currently not possible, unfortunately. See discussions here and here. Apps like Quicksilver, Alfred, and Dash are able to do it, so it is technically possible - just not implemented by George. It may become a moot point for these use cases when we get El Capitan's Split View
TLDR watch a video I created
Step 1 HotKey
Create Dedicated Hotkey Window
Preferences
>Keys
> ClickCreate Dedicated Hotkey Window
set hot key by pressing
Click to Set
(and subsequently your desired key combo)Step 2 Floating in Focus
Make the app stay above any apps that are currently in the workspace and maintain focus (in the same dialog from above)
Pin hotkey window(stays open on loss of keyboard focus)
Floating window
Step 3 Looks
When creating the hotkey terminal a new profile is created (generally named "Hotkey Window"), update profile as desired
OTHER NOTES
To enable some changes you will need to restart iTerm
You will be using a specific hot key to call up the overlay
You may also want to access preferences as well,

I'd like to propose an variant of Marc's answers. And Friedka's answer is not anymore up to date, some options were removed, some changed, I'm using iTerm
Build 3.2.0beta4
.Create and assign a hotkey

>Keys
> ClickCreate Dedicated Hotkey Window
Create a window arrangement
That's where my answer differ, Marc's answer rely on making iTerm to start with hotkey profile per default, which may be cumbersome if you need a simple standard window. Instead this answer proposes to use iterm's window arrangement.
Window
>Save Window Arrangement
Make sure this arrangement is the default
Preferences
>Arrangements
> Select the arrangement and clickSet Default
In the preference, make iterm starts with the default arrangement. :
Preferences
>General
>Startup
> SelectOpen Default Window Arrangement
Optionally tweak the hotkey window appearance
Original Answer
This command allows iTerm to work over fullscreen apps
But it hides iTerm's context menu. To access iTerm's preferences, right-click on the tabs bar and select the proper menu item; or focus on any iTerm's window and press ⌘-,.
