Answer:
For RFEM 6 and RSTAB 9, it is possible to assign hotkeys to a wide range of commands. This way, you can quickly and easily execute frequently used commands with a previously assigned key combination.
In the Options menu, select the Customize Menus and Toolbars function. In the "Customize" dialog box, you can change or add the hotkeys.
Tip: This also works for your computer mouse: If it has other buttons in addition to the left, right, and middle buttons, you can assign a hotkey to them.
