Don't use the Chrome extension for Amazon's add-to-wishlist feature
(too much privacy surrendered by installing it)
but rather go and get Amazon's button for your browser's toolbar to explicitly add any web-page as a wishlist item instead.
Some Mac magic-keys for resets and special boots etc..
Shift-Control-Option-Power : Hard Reboot ?
Option-Cmd-P-R during power-on (press before grey screen appears, hold until second start-up tone heard) : Reset NVRAM
T for FireWire/Thunderbolt Target Disk Mode for OS X 8.6 on (not Vault).
Option-Command-Escape : 'Force Quit' pop-up window.
Option-Command-Escape-Shift held for 4 secs : Unconditionally 'force quit' the front-most application.
Ctrl-Command-Power : Immediate forced soft restart. (hold power on its own for 10 secs to force power-off)
Ctrl-Shift-Power : Puts screen to sleep only, though not on Snow Leapord Mac Book Pro mid-2010, it doesn't. Try C-S-Eject.
Option-Command-Eject : Sleep. (Quick, light sleep, it appears -- maybe less than closing clamshell.)
