If drop-down ToolTips drive you as nuts as they do me by hiding what you’re reading, but you’d like to see them occasionally to check a URL for example then you can set a universal delay for all tool tips in any Mac application that has them:
do shell script "defaults write -g NSInitialToolTipDelay 4000"
(*
The delay is in milliseconds, i.e. 4 seconds shown above. I like that setting.
You have to restart for the new setting to become effective;
this is a core setting only read at startup.
