I realise that the F9 solution was posted earlier, however, both solutions suggested (manually entry or the auto-correct method) have the same “problem”, i.e. they both leave a trailing space after the zero, which, unless the zero is at the end of the number, has to be removed manually each time. This is particular annoying when your number has a series of zeros. My macro solution is as easy to implement as the auto-correct method and, once on the QAT, all that is required is a single click on the macro button for each zero required.
