Most of the help you need for the 2026 Rich Text Editor is provided in the HELP file which accompanies the Editor itself.

Please click on this button to read it:

The subject of keyboard usage is not mentioned, but you can take it that it is fully standard, e.g. Ctrl+C for copying text, Ctrl+V for pasting it (from any source), Ctrl+A for selecting everything, etc., as well as keys such as Backspace, Delete, Arrow keys and so on, exactly those you have when using any normal text editor.

That's all! Happy editing!
