Pressing left/right while the completion window is open normally scrolls through all available overloads. If there is only one overload for a method, pressing left/right ends up closing the completion list and moving the cursor forwards, normally to the next line. This is irritating as it is not what would be expected.
Can we change the behaviour to either scroll the available overloads if there are some or simply do nothing if there are no overloads.
No ... this was requested - that was the behaviour before. I said at this time it is inconsistent, but got overvoted :(
I think the problem is that we're using left/right for cycling through overloads. We should find a better way to do that, perhaps even getting rid of the need to manually choose between them by displaying them all in a single tooltip (and coalescing similar overloads to appears as default parameters?).
When trying to figure out a better way of implementing this, look at various methods on the Convert class. For example Convert.ToInt32 () has 19 overloads, 16 of which have just one parameter.
For some reason we scrapped the idea of a 'show them all' in this phase :/
(I wanted it)
closing this issue, it's a design decision
