This tip has been circulating around the traps for many years but there are still many users who don’t know it exists.
It’s a simple technique for increasing the size of the font in a document. To do this select the text and press Ctrl + ] to increase the font or Ctrl + [ to decrease the font size by one point.
To scroll through the range of font sizes available in the font dialog use Ctrl + Shift + > and Ctrl + Shift + <. If you want a font size that is not in the font dialog, type it in the font size box by clicking on the curretn font size and type the font size that you want, for example 140 and press Enter. This is a quick way of getting a very large font particularly when the options in the font dialog cease at 72 points – the rough equivalent of one inch high characters.
