Dear Allin,
This is really a very nice (and useful) feature. I have some small
suggestions to improve it. This function is a very common feature in
Internet browsers like Firefox, Safari and Chrome. In all of them (Mac
versions!) the "zoom function" is activated by pressing "Command" +
"+" (to
increase), "Command" + "-" (to decrease) and "Command" +
"0" (to restore
the original size). On Windows just replace "Command" for "Ctrl".
Just for curiosity, I checked the maximum levels of each navigator:
Firefox
max increase: 8
min increase: 5
Safari
max increase: 7
min increase: 4
Chrome
max increase: 9
min increase: 6
I hope this helps ;-)
Best regards,
Henrique Andrade*
