Hotkeys for clear input screen, switch between input-output languages, and switch translation engine

Created by: tom-vb

Describe the problem or limitation you are having when I use the translator, every time I reopen it to make a new translation I have to select the text with the mouse and delete it (I know that I could use crtl+A and then press the delete key) but there are already two steps to be done, whether I use the mouse or not. It's all about improving ergonomics and productivity

Describe the solution you'd like Being able to define hotkeys for clear the input screen, switch between input languages, switch between output languages and switch between translation engines (with the same hotkey go switching circularly, for example)

Describe alternatives you've considered I can't think of any alternative other than doing these actions using the mouse

Additional context The continued use of the mouse, apart from being slow and sometimes inefficient and unproductive, can eventually cause damage to hands, wrists and forearms.
