SafariTabs
Here is a sample configuration file for use with the SafariTabs template:
# Tab name,Tab number,key,modifier*
# * denotes optional fields
# default modifier is "option" key
Raku docs,1,r,control
Twitter,2,t
assigns ^-r-r (hold down control key and double tap "r") to activate Safari and switch to the first tab
assigns ā„-t-t (hold down option key and double tap "t") to activate Safari and switch to the second tab
PRO TIP: Use Safari's pinnned tab feature so the tabs are fixed to the left-hand side of your tab list to give tab numbers consistency between different browser windows.
