It's very tedious switching to the mouse to run the tool. I am looking for a key combination (Ctrl+Enter, F5, F9 or whatever) to run a geoprocessing tool.
Does anyone knows which shortcut is used here? Are there any shortcuts at all?
In other words, the cursor is still inside the expression text field and I want to run the script without switching to the mouse and click on the run button.
