True. Feel free to improve the heuristic.


I think a newline should break searching for existing parameters in this case.

Maybe better: "when the closing bracket is missing, a newline should
break".


When a user wants to insert template parameters, he typically has no
existing parameters at that point.
If he has existing parameters, then he uses Ctrl-Space and
Ctrl-Shift-Space to modify / verify them.

You can't use Ctrl-Space to add v2.

It does not check, if the parameter is compatible.
It sees 
pos( something.something;

Wow, you found a bug! Please report.
It happens if any function call is following the line where you try to
insert parameters, not only with Application.Minimize call.
You did not mention your Lazarus version. I can reproduce at least
with Lazarus trunk.
Is it a regression? Did it work earlier? What revision broke it?

Re: [Lazarus] Howto use Tooltip for function pos( for example?

[Landmesser John via Lazarus]

got it: insert parameters!!

Didn't work correctly with first try:


snip:

  pos(
  Application.Minimize, v2);


v2 ist put to wrong position, if the line

Application.Minimize;

follows!
