Chrome: 61.0.3163.100
Node.js: 8.9.3
V8: 6.1.534.41
Architecture: x64

Steps to reproduce:

1. Open visual studio code;
2. Open an editor with javascript text
3. Select any js code that would appear in the language docs (e.g. "Number.isInteger()" )
4. Make sure Zeal is not currently open
5. push any of the four key maps for extension

Result:
Zeal should open, but not actually search any docs
N.B.
if you push the same keymap whilst zeal is opened, the query should send perfectly
