What it says in the title.
Basically, in the PDA/station interface, Z maximizes or minimizes chat, which is great.
The problem is that zoom to universe/system also uses Z, and this interferes with smooth navigation (it's really disruptive).

Is there a quick fix to that in sight?

as of yesterday evening.. :P~

*** Vendetta 1.7.1

- mission abort button should always work in Mission Logs tab
**- chat maximize & minimize buttons' hotkeys are now 'x'**
- fixed some misc lua errors
- made mandatory tutorial fonts a little smaller at higher
resolutions
- changed positions of some mandatory tutorial menus
- changed Combat Drone back to having a larger firing angle.
- changed Training Blasters to not have as much spread.

Now that's what I call a quick fix.
