KORTLEN Mouse Studio
KORTLEN Mouse Studio is the app for your KORTLEN mouse. With it, you decide what each mouse button does.
A button can:
- press a key or a key combination, like Ctrl+C
- play a macro: a recorded row of key presses and clicks
- open a program, a file or a folder
- control music and the volume
- make the mouse faster or slower (DPI)
A button can do a different job in each program. For example, S1 can save your work in LibreOffice and open a new tab in Firefox.
A button can even do a job on one website, in every browser. For example, set up your YouTube buttons once, and they work in Firefox, Chrome and Edge. See YouTube buttons in every browser.
There is no limit: make as many macros as you like, for as many programs as you like.

Most jobs run inside the mouse itself. So they also work in games and in protected windows.
