Hotkeys are the predetermined combinations of keys on the keyboard. These combinations are appointed to actions in TextLab options and can vary at any time according to your desire. Some combinations are appointed by default.
The sequence of work with TextLab is that. You work in the text editor and while it is necessary for you to address for the help to TextLab, you select a fragment of the text and press a combination of hotkeys. The selected fragment of the text will change depending on what combination of hotkeys was used (see Action reference) .
