In the FormTitan form builder you can use a combination of keys to do things that are usually done with a mouse. So rather than reaching for your mouse to click on the toolbar, you can use the following keyboard shortcuts:
Delete CTRL+D
Save CTRL+S
Preview CTRL+P
Undo CTRL+Z
Redo CTRL+Y
Copy CTRL+C
Paste CTRL+V
Cut CTRL+X
Multiple element selection SHIFT / CTRL + Mouse
