In Toad Options I have “Enable parameter assistance” turned on (and Use inline assistance turned off).
Whenever I write a procedure/package method/function name and then “(” I get the parameter list, but once it disappears pressing the Code parameters tool tip shortcut (CTRL+SHIFT+SPACE) doesn’t do anything.
The only way to get the parameters again is to delete the “(” and write it back again.
I also tried to change the shortcut combination under Editor–>Behavior–>Key mapping…–>Code parameters tool tip, but it did not change anything.
In version 10.6.1 it worked like a charm.
