It is very time consuming to have to select individual entries and yes you can select what you can see on the screen and Match them but I can't tell you the number of times I get all the way down and hit one wrong key and I have to start again.
Alternatively there could be tick boxes (as with other far more user friendly accounting software)

If you click the 'swap' button next to the unmatched transactions box and then click 'match' this will then move them all into the matched transaction boxes and then you can reconcile from there.
