A browser that keeps up with your keyboard

1. Press ⌘/ to see every shortcut, then change the ones you want in Settings › Shortcuts.
2. In Settings › Developer, turn on developer tools for Web Inspector, the JSON viewer, responsive sizes, Clear Site Data and the list of local servers.
3. Create a developer profile in the same pane, so test sessions never touch your everyday cookies.
4. Jump between your spaces with ⌃1 to ⌃9.
5. Press ⌃⌘N to read docs beside your page, and ⇧-click a link to peek at it without leaving.

Nearly every action has a shortcut, and ⌘/ shows them all in a cheat sheet. Most can be changed in Settings › Shortcuts, and the menus, the command bar and the cheat sheet always show the keys you set.

Type into the address field and a page already open in the profile is offered as Switch to Tab first. A leading > lists app actions with their shortcuts, and Find in Tabs searches the text of the space's awake tabs.

⌃⌘N opens Split View: the current tab beside the space's last used tab, with a divider you can drag. ⇧-click a link to peek at it in a card over the page; Open in Tab keeps it, Esc closes it.

A developer profile has its own cookies, logins and site data, like every profile. It also clears disk, memory and fetch caches after every load and reloads from origin, so you see what a first visit sees.
