How to improve your workflow using Hot Corners
With Hot Corners activated you can chose to show multiple work-spaces or all the applications you have opened by pointing the mouse to the one of the corners of your screen. This setup is how I use Hot Corners (see image bellow).
Hot Corners which can be switched on and edited from the “Switchboard” System settings > Desktop > Hot Corners.

Hey I was just wondering, that is there some sort of “time-delay” function for those hot corners?
Because on one hand its quite useful, but on the other its very annoying when your mouse pointer accidentally goes to one of the hot corners.
It would be a nice feature, but it doesn’t seem possible yet or at least not easily done. Most tweaks like this are done through gesttings or dconf-editor. I can’t find anything in dconf-editor related to edge hover triggering or hot corner timing or the like. the only time settings I see are for animations. You can make things show up quicker or slower but there isn’t a time setting for triggering.
