Parameter Info only seems to work, if the cursor is inside function brackets (). This is ok, if you have "Insert pair bracket" checked in the Editor->Smart Keys Settings. You can type something like "strpos(|", then you get automatically "strpos(|)" and Parameter Info appears automatically or after pressing Ctrl+p.
But how can I use Parameter info when "Insert pair bracket" ist not checked in the Settings? Why does Parameter info not work just after typing "strpos(|"? I need the Parameter Info at that very moment, because the arguments have to be entered first and the closing bracket afterwards. Am I missing something?
(I hate using the "Insert pair bracket" option, because the closing brackets too often appears at the wrong position, so I have to manually delete it again afterwards.)
