For some reason Sublime has its spell checker disabled by default.
To enable this do to …
Preferences –> Settings –> and add the following to Preferences.sublime-settings – User
"spell_check": true
Save that file then spell check will be enabled you will see spelling errors underlined as below:
and be able to right click on the incorrect word to select right one.
OR OR OR OR OR OR as I have just found out simply enable under:
View –> Spell Check
