I usually have 2-3 terminals open when programming on Fedora, but I find it quite tedious having to click and manually bring every terminal to the front screen when I compile and run.
Are there any hotkeys / tools that will bring all terminals to the front of the screen?
You can use xdotool to achieve what you want. The main project page is over on github. You could do something like this for example:
xdotool behave_screen_edge bottom-left search --class gnome-terminal windowactivate
This will give you a hot corner in the lower left which will activate all the windows that are a member of the class gnome-terminal. This is by far the easiest method I've seen to accomplish things like this in X.
xdotool is pretty easy to use and looks to be in most of the major distros' repositories. You can check out the man page as well. There are several examples to get you started in there along with some example scripts under the github repository.
As suggested by @ramnovski, put the windows on a seperate desktop. You can switch there as part of your compile/run with wmctrl -s NUM.
If you don't want separate desktops, you can also raise a window with wmctrl -a <WIN>, where <WIN> is one of the several ways of selecting a window that wmctrl supports (matching against window title or window id).
If the titles are not unique, record the window IDs with xwininfo and store them. You can also do that programmatically, e.g. by opening a file with a UUID based name editing, have wmctrl find the window based on the UUID in the title and then discard that edit.
you should try Guake Terminal.
It appear and disappear by pressing F12,can have multiple tabs, which you can switch using keyboard shortcut.
