Many commands are already attached to simple ctrl+[key], you can also do chorded keybinding like ctrl a+b.
(In case this is your first time reading about chorded keybindings: They work by not letting go of the ctrl key and pressing a second key after the first.)
I have my Emmet: Wrap with Abbreviation
bound to ((ctrl) (w+a)).
In windows: File > Preferences > Keyboard Shortcuts ((ctrl) (k+s))> search for Wrap with Abbreviation > double-click > add your combonation.
