10.4: Modify hot corners to prevent accidental activation System 10.4
This older hint describes one way of preventing accidental activations of Exposè.

As of 10.4, however, it is also possible to add modifier keys to the hot corners in the Dashboard and Exposè panel of System Preferences. Just hold down Shift, Control, Option, Command (or some combination thereof) while selecting an option from the list.

This may be useful if you find yourself accidentally activating Dashboard, Exposè or even the screen saver when you flick the mouse to a screen corner.

Note that when a modifer key is set, you must have the key pressed before you put the pointer in the corner; it is not enough to hit the modifier key as an afterthought.

I have to agree this hint is great. I new I could add modifier keys to the function keys but had now idea I could add them to gestures and mouse clicks.

10.4: Modify hot corners to prevent accidental activation

This is a GREAT hint!

And another great example of very useful things being very un-usefully "hidden" from plain sight. How hard would it be for Apple to have included a small note inside the Hot Corners configuration window telling users they could hold down the modifier keys to activate this setting?

I love using Hot Corners to activate Expose, Dashboard and my screensaver, but often activate these things by mistake with when mousing around the screen. It won't happen again thanks to this hint!

It also occurs to me that a step even beyond this would be the ability to have multiple actions associated with the SAME Hot Corner, depending on the modifier keys being pressed...

The free prefpane CornerClick can do what you're asking for: multiple actions for a corner depending on the modifier key pressed. There's even a handy "hover for two seconds" modifier, which eliminates most "accidental" activations.

Thanks for posting this. I'll go give CornerClick a spin right away. Looks promising...

Um, there is a note
Authored by: rsnyder on Aug 02, '06 09:25:24AM

At the bottom of the Dashboard & Expose preference pane there is the following:

"For more shortcut choices, press the Shift, Control, Option, or Command keys."

At least there is on 10.4.7.

Authored by: RussellK on Aug 02, '06 01:03:58PM
Ahh...but (for whatever reason) I've been accessing my Hot Corners via the "Desktop and Screensaver" preference pane. And there's no note there. So is this better or worse? Better because there is a note somewhere , but worse because despite the fact that they realized this was worthy of a note they failed to put it everywhere the feature can be accessed...

Yes, but the note refers only to "shortcuts", and this was already well known.

Great hint. Now I can have real use for the hot corners.

I find CornerClick's 2 second delay too long. I use Quicksilver instead to set up a corner trigger with a 0.5 second delay.

10.4: Modify hot corners to prevent accidental activation
Authored by: a153957 on Aug 03, '06 01:26:00AM
Well, indeed a useful hint, and:
http://greg.vario.us/cornerclick/

"Since some people have requested that the 2 second delay used for delayed hover actions be reduced or configurable, I modified CornerClick to allow you to change that delay. It is not part of the GUI yet, and I'm not sure how I want to do that yet either (whether the delay should be customized per-action, or global)."

Please Apple, add this to the dock!
Authored by: xianman on Aug 02, '06 02:36:52PM

I've written to Apple numerous times in the past asking for this feature with Dock. Maybe if more people asked Apple for this rather obvious feature we might see it in Leopard. Come on people, I don't want to wait until Mexican Hairless!

10.4: Modify hot corners to prevent accidental activation
Authored by: artMonster on Aug 02, '06 05:26:53PM

I have the scroll ball on my Mighty Mouse set as button three and use it to activate the Desktop. By using a modifier key to prevent accidental activation, it also seems to have solved another problem I have had with this mouse. Left click now <i>always</i> results in a left click (before it would often register as a right click), and pressing the scroll ball (without the modifier key) now opens links in a new window.

this is both really cool and kinda sad..
Authored by: cynikal on Aug 03, '06 09:03:22AM

cool because last night i needed to use my middle mouse button (aka the scroll wheel "button") cuz i started using SketchUp, and it's normally set to "Show Desktop" via Expos.. it would suck if i had to set/unset this depending on whether i wanted to use the app.. but with this, i can not only set a modifier to have the best of both worlds, but this also prevents accidently tripping Expos...

it's kinda sad though that such a cool feature is somewhat hidden, in that it's not obvious for someone to actually try this.. why doesn't apple put a little note or something to make people aware of this? i mean this has been around since 10.4.0 ?? and it took until 10.4.7 for someone to post a hint to this? i'm all for easter eggs and hidden goodies, but this is too useful to be in that category..

Sorry but there is "For more shortcuts choices, press Shift, Control, Option or Command keys." at the bottom of the window.
Even if it's not obvious enough for you, it's not hidden.
