I also use ImageJ to measure leaf area.  I assume you want to see the
fonts so you can record the data.  Why not just add the data to the
results table?  Then you don't have to type anything.

If that's not an option, then this demo macro has many examples of
setting the font: http://rsb.info.nih.gov/ij/macros/TextDemo.txt
