Making fonts larger in apps under Lion While there is no system-wide way to make all fonts larger under Lion without leaving native resolution, many individual programs do have a way to make text and various elements larger on the screen. Unfortunately, this varies from one program to the next.

If the goal is to make text appear larger in all programs, can we put together a guide to zooming in the various apps in Lion?
Google Chrome

Its own UI, not web pages

The following settings in TinkerTool affect the following pieces of Chrome's own UI:


Chrome address bar, i.e. URL:  System in TinkerTool (default font: Lucida Grande; largest size possible is 16 pt; larger sizes are truncated)
titles of tabs:  Help tags (default font: Lucida Grande; largest size possible is 13 pt; larger sizes are truncated. Bold is ignored, it's always Regular)
Chrome's ex-Wrench menu (top right corner): Messages (default font: Lucida Grande; upper limit is something like 24 pt, further increasing the number has no effect)


Web page content


Default zoom: Wrench > Settings (⌘ ,) > Show advanced settings > Web content > {Font size, Page zoom}. Both also affect how Settings page is zoomed. 
For a particular site: ⌘ + / ⌘ -
