While this is a standard feature on the aforementioned OSes, the concept is foreign in Windows, as there is no built-in way to set hot corners, although you can use keyboard shortcuts to trigger the same actions.
These are not exclusive; you can assign the same action to more than one corner. So one possibility I have seen in use is to have both top corners display/select Workspaces, and both bottom corners display/select Windows. Of course, in the extreme case you could assign a different action to each corner.
First, if you select "Icon visible" to enable click for hot corners, the icon(s) actually overlay the panel. That may look a bit confusing, but it actually still works ok, the area just around the icon becomes the Hot Corner click surface, and going there with the mouse does not bring up the panel.
This can make it a bit challenging or surprising if you have "Hover" enabled on whichever two corners border between the two displays. For most people, until now "Hover" has meant "slam the mouse over to the corner", but when you have multiple displays, doing that on the border where the second display sits will just send the cursor flying off to the other display, usually without triggering whatever the hot corner is supposed to do.
So that pretty much covers it for Hot Corners. Not terribly complicated, but very useful and wonderfully flexible and configurable. I generally have mine set up with Workspace and Windows on the top corners, Desktop on the bottom left and Run gnome-terminal on the bottom right.
Currently there is no support for corners (only edges) and it was built for one-monitor setup (obviously, one cannot cover all the bases within 7 hours of creation), but those features might be available eventually in the future.
We may also show the % of the battery, add a date with the day and hour, and show week numbers. We may also activate hot corners, which will display the activities view with all active programs if we move your mouse to the top left corner of the screen.
There is also a new advanced expert setting which lets you select items without the need to press any key or button at all! It is called Hover Mode and it can improve selection speeds significantly if you know your menus by heart. It is also useful if you open your menus with other means, such as Easystroke or hot corners.
I agree with this. I move show all desktops for me to the bottom left cause I have a habit of mousing too far into the top corners and activating it when I'm simply trying to close a window, access the start menu, or trying to access logoff / restart on the top right. I also have KRunner set to activate from the bottom right corner. These were my personal needs so I didn't bother to ask for changes to be made.
I, for example, do not care one bit for hot corners (period) and I always disable them. In KDE this is incredibly simple to do--where as Gnome you have to install extra software just do disable the default hot corner.
The Deepin Desktop also has a nifty hot corners feature on the desktop. With this feature, you can set each corner to a specific action, such that when you hover your mouse over a particular corner, the configured action will occur. Available actions are:
To set the hot corners, right-click on the desktop and select Corner Settings from the pop-up menu. You can then hover your cursor over one of the four corners and select the action you want associated with that corner (Figure 6).
A search window makes finding applications fast. As you type letters, a list of icons for matching applications appears. Click the gear button in the far right of this top row to open a GNOME Menu settings panel. It is here that you can turn on/off numerous features such as activating hot corners.
My son said this is a feature similar to those of Apple, and that for him this feature of shrinking and growing windows/icons etc is annoying. Whether or not it may be annoying to all, it is annoying to some, and it is certainly made worse by the G1G1's tiny screen as opposed to a 19 inch Mac.
Update: I have recently realized that for many apps, in my experience around 60%/70% of them, you can also just double click on the title bar and the window gets maximized as well. For the apps where this does not work (e.g. iTunes or some apps which have no title bar) you can still double click on opposite window corners as explained above.
You can disable hot corners in the desktop menu of the system settings. To turn off at least some of the effects, you can use elementary tweaks, which will give you an additional panel in the system settings.
Hot corners are probably cool but doesn't work very well with a tablet. I tend to forget about them, then I quickly remember as I take back a mouse. Kubuntu comes with a predefined hot corner to show all windows, it can be deactivated this way:In the settings: Desktop Behavior > Screen Edges > deactivate the top left corner "present all windows"
I'm having the same problem with both KDE and dwm, I tried switching to newer virtualbox betas and compiling the client stuff myself to no avail. Still seem whenever I drag the mouse jumps to corners. Disabling guest additions works to fix it, but it's a terrible solution. Anyone have a better fix or other ideas? Should I report this upstream?
Reporting the same issue here. Visible pointer stays in the same location, but the mouse registers location at corners/top/bottom sporadically. I've found it happens in Gnome, XFCE, and KDE, and as with everybody else disabling the vbox modules seems to fix it. 2b1af7f3a8
