Save yourself some clicking and press a hotkey.

First only the "e" button made sense in my head but I also add the "a" button in IP4 Addresses to assign selected IPs.
Next one was "d" button to deploy selected servers.
Afterwards the navigation was enhanced:
Use "u" to get "Up to Parent" if possible. I also added the left and right arrow keys for page navigation (see gif below).
After consulting other users, ALT+Number (1-7) hotkeys are now added to switch between category tabs (see gif below).

For "e" I limited the execusion to IP Space, DNS, Devices and Groups and will not edit the code on configuration level.
The "a" hotkey is limited to the Addresses Tab of the Network page.
Deployment with "d" only makes sense in the Servers tab.

To prevent accidental hotkey pressing while typing the hotkey are disabled while in a text, search or dropdown box!

here is an example for editing the current:

here is an example for navigation (use "u" to get "Up to Parent"):

example for mouseless tab navigation (use "ALT+1" for My Ipam, "ALT+2" for IP Space and so on)
Watch out though while in a text, search or dropdown box, hotkeys are still disabled.
