@ DayWalker - thanks for suggesting Vimium web-browser keyboard extension for Firefox, but as it sadly doesn't work with Wayfarer (as yet? ) we can't use this functionality on Wayfarer, though it would be a nice feature enhancement if it did in the near future or some other script was written to allow this functionailty.

It was probably somekind of early version of Vimium web-browser keyboard extension that was incorporated in Firefox's Tools/Settings that I came across that I found quite useful, that has since been removed but that had similar functionality incorporated in it, that this extension now has and can be used with numerous browsers, sadly not Wayfarer as yet.

@ jacadcaps - do you mean Vimium web-browser keyboard extension could be added to Wayfarer by way of a script?
