Keyboard shortcuts for coding

[JBGruber]

It would be great if it was possible to control DNA with keyboard commands to increase the speed of coding. Here are a few suggestions:

• By defaults, the cursor should be in text already or maybe as soon as you press an arrow key
• Navigation through text should be possible using arrow keys.
• Text selection could be done by holding shift and using arrow keys (this is already working but only when some text is already selected).
• Once text is selected, control + 1 should create a statement type 1, control + 2 should create a statement type 2 and so on.
• once the statement window is open, the arrow keys should select values from the first dropdown menu; 1-9 should select values directly; left & right arrow key should un-/select boolean values.
• tab should jump to the next box in the statement window.
• Esc should close an open dropdown menu, a second Esc should close the Statment.
• Page Up/Down should switch between documents
• Maybe space or another button could be used to jump to the position of the next instance of a regex highlighted term.
