Because of bank feeds I only go in to reconcile the bank accounts on a monthly basis to match the ending balance to the bank statement, and because I am used to the CTRL a shortcut highlighting all in the selected area, I press it to highlight all the closing statement balance and it actually unticks/ticks everything showing, regarless of it being matched up to a bank feed. This is really painful to do so easily by mistake, as I then have to go back and find which ones were unpresented.
