Warning:  In every window where there are some input fields to permit the user
	  to insert text a mechanism of select-cut-copy-paste is
	  available. To provide this mechanism there is a (hidden) clipboard
	  where is copied the text selected by the user.

Right arrow - Moves the cursor ( = virtual pencil ) to the right in a line of
	     text and when it reaches the end of a line 
	     1) Moves it to the next line if the cursor is inside
		a multiline input field,
	     2) else moves the cursor to the next input field

Left arrow  - Moves the cursor ( = virtual pencil ) to the left in a line of
	     text and when it reaches the begin of a line 
	     1) Moves it to the previous line if the cursor is inside
		a multiline input field,
	     2) else moves the cursor to the previous input field

Up arrow    - Moves the cursor to the previous line if it currently stays
	      at the 2nd, 3rd, 4th, ... line of a multiline input field, else
	      moves the cursor to the upper input field.
  
Down arrow  - Moves the cursor to the next line if it currently stays
	      inside a multiline input field but not at the last line, else
	      moves the cursor to the lower input field.

Shift+Home  - As Home, but the text is (de)selected while the cursor is moved.

	      between different input fields

Ctrl + n    - As Down arrow, but it is not very suitable to move the cursor
	      between different input fields

Ctrl + k    - Erases to the end of line (next '\n' character) or erases
	      a single '\n' character (corresponding to an empty line).
	      These deletions are all concatened into the clipboard.

Ctrl + c    - Copy the selected text to the clipboard

Ctrl + x    - Copy the selected text to the clipboard and delete it
	      (i.e. cut the selected text)

Ctrl + w    - The same as Ctrl + X

	      of the cursor

Ctrl + y    - The same as Ctrl + V

Ctrl + z    - Undo. This is a single-level undo mechanism, but all adjacent
	      deletions and insertions are concatenated into a single "undo".
	      Often this will undo a lot more than you expected.
