Hi All, Here is something practical you can use today. Enlargement should go up to about 7 or 8x to be realistic. The browsers go to about 4x. Here is how to fix that in Firefox. There is a address about:config you insert as the url. Now there are two parameters of interest. toolkit.zoomManager.zoomValues zoom.maxPercent The first has default settings of: .3,.5,.67,.8,.9,.1,1.1,1.2,1.33,1.5,1.7,2,2.4,3 The second is set to: 300 I reset them to .67,.8,1,1.25,1.5,1.75,2,2.5,3,3.5,4,5,6,7 and 700 resp. about:config warns you about violating the warranty but I ignore it. You can even read legal disclaimers with at juice. Wayne On Wed, Jan 20, 2016 at 11:11 PM, Srinivasu Chakravarthula < lists@srinivasu.org> wrote: > Indeed great discussion.
