A GNOME Shell Extension which allows you to control and navigate Gnome Shell environment through the corners and edges of your monitors. But not just that, it adds many unique actions with keyboard shortcuts too.
This extension is based on the original Custom Hot Corners exetension, but not much of the original code remains.
- Gnome 3.36 - 43 compatibility
- Hot corners with adjustable barrier sizes, both vertical and horizontal independently and usable as hot edges
- Mouse buttons and a scroll wheel can be used as action triggers
- Each trigger can be set to work only if Ctrl key is pressed
- Each direcion of a scroll wheel rotation is configurable independently
- Each trigger can activate one of many actions including command execution, workspace and window navigation, window control, power manager actions, sound volume control, MPRIS player control, color filters (for windows and global), accessibility features and more.
- Preferences window provides an app chooser dialog for "Run Preset Command/Activate App ..." action configuration. You can choose and modify exec command of chosen application, or app ID which will work the same way as if click on the app icon in Dash or App Grid.
- Each corner's area reactive to mouse clicks and scrolls can be extended both horizontally and/or vertically to cover most lenght of the monitor's edges. If the adjacent corner is not set to expand in related direction, the corner can be expanded to 7/8 of the monitor's width/height. If two adjacents corners are set to expand to each other's direction, then it is 1/2 of the length for each. You can see the result of expansion settings using the Make active corners/edges visible option.
- Fallback hot corner triggers as option - can be used on virtualized systems with mouse pointer integration where pressure barriers are being ignored.
- Multi-monitor support. If you open preferences window, each monitor shows its index in the top left corner.
Monitor 1settings are always applied on the primary monitor, the rest keep the order as set by GNOME.- You can set global keyboard shortcuts for any actions on the menu, except for those available natively in GNOME Settings.
- You can create up to 4 Custom Menus with your own selection of actions and use them as a single action.
Window thumbnails are scaled-down window clones that can be used to monitor windows not currently visible on the screen. Default position for the thumbnail is bottom right corner of the current monitor. You can create as many clones as you want and place them anywhere on the screen. Each thumbnail can be independently resized, you can adjust its opacity, even change its source window. When the thumbnail's source window close, thumbnail is removed too.
Double click - activate source window
Primary cLick - toggle scroll wheel function (resize / source)
Scroll wheel - resize or switch source window
Ctrl + Scroll wheel - switch source window or resize
Secondary click - show fullsize window preview and toggle sowing preview on mouse hover
~~Middle click - Toggle icon view instead of the window thumbnail~~ This feature was removed for now because of complications
Shift + Scroll wheel - change thumbnail opacity
You can install this extension in several ways.
The easiest way to install Custom Hot Corners - Extended: go to extensions.gnome.org and toggle the switch. This installation also gives you automatic updates in the future.
Download the latest release archive using following command:
wget https://github.com/G-dH/custom-hot-corners-extended/releases/latest/download/custom-hot-corners-extended@G-dH.github.com.zip
Install the extension (--force switch needs to be used only if some version of the extension is already installed):
gnome-extensions install --force custom-hot-corners-extended@G-dH.github.com.zip
Then restart GNOME Shell (ALt + F2, r, Enter, or Log Out/Log In if you use Wayland). Now you should see the new extension in Extensions (or GNOME Tweak Tool on older systems) application (reopen the app too if needed to load new data), where you can enable it and access its Preferences.
You can also enable the extension from the command line:
gnome-extensions enable custom-hot-corners-extended@G-dH.github.com
If you want to test the latest version from the Github repository (which is usually working well enough as it's the code I'm currently using on my own system), you can use following guide.
Make sure you have installed packages prviding following commands: glib-compile-resources, glib-compile-schemas, git
git clone https://github.com/G-dH/custom-hot-corners-extended.git
cd custom-hot-corners-extended
make install
Custom Hot Corners - Extended has also AUR repository maintainer (but I know nothing more about it): https://aur.archlinux.org/packages/gnome-shell-extension-custom-hot-corners-extended
After installation you need to enable the extension. Only direct installation from extension.gnome.org loads the code and enables the extension immediately.

Contributions are welcome and I will try my best to answer quickly to all suggestions. I'd really appreciate corrections of my bad english.
You can contribute with translation to your language, source .pot file can be generated using
make pot
command within the cloned git repository, then you can use Poedit application for translation and export to .po file.

During development of this extension I was inspired by many extensions and other developers, I'll try to name the main contributors to my code:
- True Color Invert - useful extension with confusing name, which brought me to shader efects and whoose modified code I use for 'Invert Lightness' action and other color filters.
- BaBar Task Bar - nice panel task bar which window preview I initially used as a base for my 'DND Window Thumbnail'
- GS Connect - CHC-E relies on the keybinding module copied from this great extension.
- Simon Shneegans - amazing developer with skill and style who provided me new Make files for my extensions and a lot of inspiration.
- And, of course, the original 'Custom Hot Corners' extension that I forked based on which this extension grew.
