One of OS X’s notable features is its Hot Corners service, where by moving your mouse to a designated corner of your screen you can activate one of several designated tasks, including sleeping your system, preventing sleep, triggering Expose views, and more. These options undoubtedly have their benefits; however, there is also the problem where the default approach for assigning hot corners makes them too easy to trigger.
Even for a well-trained individual, having a hot-corner enabled that makes a change to your current view (such as enabling Expose), has the potential to be a distraction. As a result, you may find yourself avoiding the corner that this action is assigned to, since inadvertent triggering may disrupt your workflow.
- Go to the Mission Control system preference, and click the “Hot Corners…” button.
- Click the desired hot corner menu to show its options.
- Hold a modifier key (such as Command) before selecting your desired action.
Any modifier key will do (Command, Option, Control, or Shift), and even combinations of them will work.
You can hold various modifier keys (in this case the Shift and Command keys) when setting a hot corner, in order to require these be pressed for the specified action.
Unfortunately you cannot layer different actions on the same hot corner with multiple modifier key combinations (ie, using Command and Option separately in the same hot corner will not work), but having these should give you custom options for triggering hot corners purposefully.
Great tip! BTW, it works the same in Desktop & Screen Saver (shown) and Mission Control. Just the Hot Corners button is in a different place.

Is there a way to block Desktops bar showing on top of Desktop when moving or dragging items to the top of Mac Finder in Mac OS X 10.11.x El Capitan?
Thanks, Topher. This had been annoying me for a long time now.
