• (2022-05-17) Clarissa Toyad: Doesn't work anymore. You can set the shortcut to anything, but pressing the shortcut doesn't turn anything greyscale. Maybe it needs to be updated.
• (2022-02-08) Brooklyn: No matter what combination I used, it didn't work- was looking forward to this...
• (2021-08-30) Juri Novik: работает Shift+G при опции "на выбранных сайтах"
• (2021-02-22) Zach and Jadyn Stewart: The short cut didn't work at first but I had to refresh the tabs I had open before I installed the extension before the short cut started working.
• (2020-12-03) Leonid Androshchuk: Very nice neat tool but not always works
• (2019-08-13) Blake Nelson: Works. If you're having issues, it's because you're trying to use it on a web page you had open before installing the extension. Try refreshing that page and then using the hotkey. :)
• (2019-08-01) Jake Larsen: Shift+G combination does not work, nor does Ctrl+G or Alt+G or several other attempted combinations. Needs an on/off setting outside of a keyboard shortcut.
• (2019-06-28) Mick Simmons: Doesn't work with Shift, CTRL, ALT plus g. How do you create other shortcuts (eg. ctrl + alt+ g)??
• (2018-06-29) Abhi Shah: not working in Chrome 66
• (2018-05-25) Mara Kalat: Would be neat to also have a toggle from the icon and not just a keyboard shortcut. Aaaand the shortcut doesn't always work on the first try. But it does the job, I guess?
• (2018-01-24) Kyle Huston: didn't work on macos Chrome
• (2017-02-20) Jake Mitchell: Doesn't work.
• (2016-12-21) Patrick Boatner: Works just fine. Even allows customizing the shortcut.
• (2016-12-01) Aaron Troia: doesnt work, is this only windows compatible? Also, allow users to create their own shortcut.
• (2016-11-22) Perfect for work!!
• (2016-09-21) Doesnt work
• (2016-07-13) M Ng: This works, except the developer should have made the short cut combo key less common. If it doesn't work for you, it's because you have another extension that is using that combination. Try changing it to Ctrl+G but then use Ctrl+Alt+G seems work for me. The other fail safe is to put your browser in dev mode (F12) then use the default Shift+G which should work.

Latest issues

• (2020-11-11, v:2.0) Andrew Wainwright: Please tell us how to turn it on.
  Clearly many of us have had the same issue. The Extension page says it is on (slider to the right), but when I click on the Extension Options, where you can change the hotkey, it says status: OFF. No amount of Shift-G or any other combination I've tried changes this. (And subpixel rendering is still making everything unnecessarily psychedelic.)
• (2018-05-06, v:2.0) How to make this work
  I have tried pressing shift-g and ctrl-g and nothing is working. How do I make this work?
• (2018-01-29, v:2.0) Charlie: Doesn't Work
  Shift-G does not do anything and I no changes I make alter this.
• (2017-01-10, v:2.0) Veronica Taylor: Grayscale Add-On
  Cannot activate this add-on. Shift-G does not work.
• (2016-11-10, v:2.0) Zhian Kamvar: Add support for local html files
  The extension works as it says. A nice improvement would be to (if possible) add support for local HTML files (files://localhost/...)

• (2015-11-02, v:2.0) Miguel Ferreira: Doesn't work
  When I press the shortcut key nothing happens.
• (2015-10-10, v:2.0) Tim: Can't make 'Alt + Shift + g' to toggle Grayscale Tool on/off
  Hello, Thanks for your nice work. This extension saves my eys. However, I prefer to make 'Alt + Shift + g' to toggle Grayscale Tool on/off, but the extension options cannot do this. My suggestion is, would you please make the extension work with Chrome extension keyboard shortcuts so that we can define combo keyboard shortcuts, like alt + shift + g. *** NOTE *** If you go to chrome://extensions/, you'll find at the very bottom a link to "Keyboard shortcuts" from where you can set your own shortcut key to whatever you want.
• (2015-09-04, v:2.0) Blue Wolf Zero: Must delete
  I can't delete it!!!
• (2015-04-02, v:2.0) shortcut not working
