Right now if I type in $ into Jetbrains PhpStorm IDE, it will display a whole bunch of suggestions (e.g. variables that have already been declared) which slows down my typing.
Is there a way to configure PhpStorm to NOT do this? In other words, turn off auto-complete or only do auto-complete if I press Ctrl+Space and not when I just type in $?
Disable code completion?
See Settings/Preferences(depends on OS) - IDE Settings - Editor - Code Completion
There you should find an option Autopopup code completion in (ms)
If the check box is not selected, PhpStorm will not suggest code completion automatically.
