The Fun Extras - Set Three
57. Zooming (link to comment)
This video shares some handy shortcuts for zooming. I wish I could remember these and get used to using them myself, but somehow they have not been committed to memory yet. Such a shame because I do like them!
Double click on the Zoom Tool or Alt+Ctrl+0 for 100% (actual pixels)
Pressing Ctrl++ will increase the size and Ctrl+- will decrease.
