Make the keyboard TAB works

Actually, using TAB when writing a note will jump to the other section in MYLE.

Consequently, it's impossible to add section in a note to add space at the same lenght, like in Word to add text like in a column :

BLABLA 12 6
BLIBLI 10 8
BLOBLO 3 9

I was obliged to use my spacebar to add a few blank between numbers.

Adding a key, like SHIFT+TAB could add 5 spaces to let the writer enter the datas in a convenient way.
