Crusper

Crusper is an application you can use to create various shortcuts when clicking a corner of the screen with the mouse, such as opening a file or folder, viewing a personalized message, or going straight to the desktop. It features intuitive settings for users looking to boost their productivity by putting together such shortcuts for important events.

Compatibility issues with later Windows

Before proceeding any further, you should be aware that the program hasn't been updated for a really long time. It didn't work on newer Windows versions in our tests (starting with Windows 7) and we failed in our attempt to resolve this issue by trying to run it in compatibility mode for older editions.

Software requirements and screen calibration

A notable aspect about setup is that you must have .NET Framework installed, since it was developed with the aid of this tool. Moreover, administrative privileges might be required at program startup, especially if you installed it in the default directory.
Right after installation, Crusper enters fullscreen mode and asks you to perform a calibration by moving the mouse and clicking the top and bottom right and left corners of the screen. This configuration can be adjusted anytime from the main menu.

Set corner shortcuts and customize preferences

It gets integrates into the systray at startup and must remain running to keep the screen corners hot. When it comes to shortcuts, you can launch a program (.exe), open a file or folder, go to the desktop, type a phrase or launch a website, as well as restart, shut down or log off the computer, or forbid any of these four actions.
After picking a shortcut, you can indicate the screen corner, manually or automatically click it, and enter a script name and description. Worth noting is that multiple shortcuts can be specified for the corner, but you should make sure there aren't any conflicts. (e.g. shut down and forbid shutdown). The shortcuts can be edited. Furthermore, you can enable auto script playing and ask the tool to autorun at system startup.

Straightforward quick launcher

As previously mentioned, we failed to get Crusper up and running on newer Windows, but it still works well on older editions. CPU and RAM usage was insignificant in our tests. Thanks to its approachable interface and options, the program can be easily used by anyone.
