Back in kmymoney 4.x, the Amount field in the transaction form always had its entire content (by default: "0,00", or previous amount when editing) selected whenever it was activated by mouse or by tabbing. A new amount could be entered immediately, overwriting the default/previous content.
Now (kmymoney 5.1.2), the content of Amount field is not selected when entering it. The cursor is placed at the beginning of the field at "|0,00".
Therefore, I need to select the entire content of the field before entering an amount (unless I want to enter an amount like "10,00" or "20,00").
The Amount field should go back to having its entire content selected to save the user from selecting manually in almost all cases.
