Same, I&#x27;ve had two of them in use over a year and other some fading on the key letters they are exactly as good as the they where new and I replaced MX Blue mechanicals with them so it&#x27;s not like I was coming from a bad keyboard.<p>I use the for&#x2F;back buttons to bind all sorts of things (currently &quot;build JS&quot; and &quot;build CSS&quot; on front end side of project), The toggle in the middle I&#x27;ve never found a use for, I played with using it to tab through windows but honestly it&#x27;s slower to move hands of keys than it is to just map the same functions to keyboard shortcuts.<p>On linux I have mapped the zoom to scroll&#x2F;up down in the past but I&#x27;m so used to hitting pgup&#x2F;pgdn it never stuck.
