As addicted user of shortcuts, I recently placed my Cadence Virtuoso customizations on a blog (easy maintenance, easy uploading etc.). You can find it at

Playing with analog circuits for over 10 years, I got accustomed to Cadence tools and wanted to change a few things. It all started with the desire to use Alt-1 to toggle metal1 visibility, and Alt-2 to toggle metal2 visibility. Then I started to want other posibilities, get rid of the LSW window, raise the library manager etc. I quickly grew out of Alt-… keys and introduced Alt-a Alt-b combinations, typed after each other. The file below contains a lot of my current customizations but cannot be used directly. It needs a few modifications to localize the right paths and variables. So it is necessary to have skill knowledge to install. A installer is not part of the game.
Example 1: switch to schematic view when in a Virtuoso layout window: Alt-i : go to library manager mode Alt-e : switch to schematic view of this cell Alt-e : switch back to the layout view
Example 2: select all single vias in a Virtuoso layout window: Alt-f : go to filter mode Alt-v : select vias (in the visible part of the active window) Shift-Alt-b : filter smaller items (works with transistors, vias, rectangles etc.) repeat Shift-Alt-b until you get only the single ones
