• VSCode Version: 1.23.1
• OS Version: Windows 10 x64

Steps to Reproduce:

1. Start typing a method with multiple signatures.
2. After entering parameters, try going down using arrow keys.
3. Instead of cursor going to next line, it cycles the signatures in the parameter hint popup.

Does this issue occur when all extensions are disabled?: Yes

In the above screenshot, when the cursor is after the last parameter, i.e. after s of this.totalPages, I cannot go to the next line without dismissing the hint.

This popup and it stealing keys is annoying as hell. I don't want to completely disable it but I don't want to hit esc key everytime I enter few chars. It'd be nice if:

• it didn't steal focus
• can appear after a delay
• or disabled but can be manually invoked with a key combo
