alt Hacker Newsstrange. Some keyboard shortcuts in os x are kinda weird and not intuitive to linux or windows users, but they are there. It's totally possible to use mac without trackpad. even cmd+tab switcher has a lot of hidden (but googlable) things: while still holding cmd after initial cmd+tab, you can close apps with q, switch to other apps with tab and (cmd+)shift+tab or left/right arrows, show app windows with down, etc. There's also a cmd+` for switching between one app's windows. I still find that distinction weird from usability perspective, but it's not too hard to adapt to it.
> totally possible to use mac without trackpad
As I discover every time I have a mouse fail, it is exceptionally difficult to use a modern Mac without a pointer device because at some point, it became quite difficult to get from (eg) the settings nav panel to the settings panel. I can CMD+SPACE to open spotlight, type 'Settings' to get to a settings panel, type 'Bluetooth' to open the bluetooth settings, and where I feel like I _should_ be able to `Tab` or `Enter` into the devices list, or have SOME way to navigate over there, the only way I've found to be able to is to plug in a physical mouse
Moreover, I occasionally encounter modals that won't let me tab to their action buttons, requiring a pointer device click to dismiss
