Co-sign. This is one of the reasons I’ve always loved NetNewsWire as my RSS reader and few things have been able to displace it. Everything is doable by keyboard, and the keyboard commands are extremely logical and intuitive. You can FLY through your backlog.

Excel is the same way. I’ve been an excel power user as well as a Sheets power user and the latter just never managed to enable the level of speedy keyboard navigation Excel could. I can almost work blindfolded in Excel.
