Set hotkeys for chrome pages

[Dale]

Hello,

I want to set hotkeys to - 
1) Open the 3 dots of chrome - at top right of the browser
2) And also want to set new custom hotkeys for opening the task manager of chrome
3) And to open extensions page of chrome (and also if possible then scroll to bottom of extensions page after opening it).

Want to set custom hotkeys for all 3 above.
For the chrometaskmanager I want to set the custom hotkey different from the inbuilt chrome hotkey to open chrometaskmanager by SHIFT+ESC.

Thanks.
