If users would like to increase the type size of Brief Accounting or Brief EnCounter, they must use the Zoom feature in OS X. To enable this:
Turn on Zoom via Universal Access under OS X preferences.
Choose the Apple menu > System Preferences
Click Universal Access
Seeing tab set Zoom to On
Click the Options button
Set "When zoomed in, the screen image moves" to "Only when the pointer reaches an edge".
Now, with Brief EnCounter or Brief Accounting in the foreground, hit Command Option and the "+/=" key to increase the BA window
Hit Command Option and the "_/-" key to decrease the size again.
This will increase the size of BA/BE but will zoom out again for everything else.
