GNOME 3 lets you show all your activities by moving the cursor to the top-left corner of the screen, a feature known as an active corner. Windows 10 has a similar feature called Task View, but you have to click its icon or use a keyboard shortcut. If you use Linux frequently and miss the active corner, or if you like the idea of moving the cursor to summon Task View, what you need is a small executable called Tiny Hot Corners.
I admit I'm too rusty to assimilate sudden changes in an interface. Apparently I'm not the only one who feels this way, and Microsoft had to learn this the hard way after the launch of Windows 8. However, what the company did in Windows 10 wasn't enough, and one of the first things on my list is installing the fabulous Classic Shell. If these unexpected changes are complicated for users who go from one version of Windows to another, imagine the problem for those who invest much more time in Linux.
The Solution
One of those users is Tavis Ormandy, who is part of Google's Project Zero hunting vulnerabilities. In his specific case, what he misses are the active corners of GNOME 3 in Windows 10, and to cover that absence he created Tiny Hot Corners. I'd love to share details about its interface and advanced configuration... but there simply aren't any. The Tiny Hot Corners executable stays in RAM memory taking up less than 500 kilobytes, and every time you move the cursor to the top-left corner, Task View will activate.
Configuration and Notes
The only way to change its basic behavior (say, move the active corner) is to modify its source code and then compile. The only .exe that Tavis delivers on GitHub uses the top-left corner. Tiny Hot Corners is portable, has no installation, and if you want it to start with Windows 10 you'll have to create the necessary shortcuts yourself. The key combination that closes the process is CTRL+ALT+C, or you can use the Task Manager as an alternative.
