I mean, they could probably start by having actually useful keyboard shortcuts, instead of 2 pairs of shortcuts that do exactly the same thing (`Ctrl+L` and `F6`; `Ctrl+K` and `Ctrl+E`), and the four together doing almost exactly the same thing (the first two focus the omnibar, the latter focus the omnibar and set it to search mode, which is equivalent to focusing the omnibar and typing "?" then pressing `Tab` or typing "<default search engine alias>" and pressing Tab).

At least from my own usage, I can identify many common usage patterns that would benefit from shortcuts that focus the omnibar and set it to some special mode, just like the VSCode command palette does (e.g. `Ctrl+Shift+P`, `Ctrl+P`, `Ctrl+Shift+O`, etc.). In fact, I don't know how a WebExtension-enabled VSCode-based browser hasn't popped up yet.
