Keyboard shortcuts are fast and awesome. But there are still many actions that require you to reach out for the mouse. Homerow solves this by allowing you to search and click on buttons and links on the screen. It's similar to Spotlight, but for the macOS user interface.
Homerow is like the classic Mac app, Shortwave. It's great for when your hands are already on the keyboard and you want to trigger buttons without moving your hand back to the trackpad. For example, when I finish typing this, I will trigger Homerow to click the orange "Post" button to submit this review.
This is the best app for quickly clicking almost anywhere via the keyboard, which is particularly useful when there's no keyboard shortcut (or I can't remember the shortcut). Minimizes switching between keyboard and mouse.
Homerow is one of the first apps I install on a new Mac. You can click any element on the screen by fuzzy searching. Dragging and clicking with a mouse or trackpad feels so inefficient now, when you can achieve what you want via a simple hotkey.
