Keymou—pronounced as "keymouse" minus the "ess" sound of "mouse"—lets you control the mouse pointer with the keyboard. With Keymou running, you can use the keyboard (or menu items) to move the mouse, scroll, click and double-click, right-click, and even find the mouse's onscreen location.
When you first launch Keymou and open its settings, you'll see a number of default actions:
You do not need to keep any of these actions as they are—you can rearrange them, modify them, change their keyboard shortcuts, or even delete them. They are there just to give you a sense of what Keymou can do.
General Tips
The entries here behave much like a list of files in the Finder. You can select any single action with a click, or select multiple actions by holding Shift (contiguous selection) or Command (non-contiguous selection) before clicking. You can rearrange with a click-and-hold followed by a drag, then release the item at its new location.
To add a new action, click the plus sign at the bottom left of the window. To delete an action, first select one or more actions, then click the minus sign at the lower left of the window.
To assign a keyboard shortcut to an action, click in the box at the top right of the action area, and press the keys you'd like to use. To delete a keyboard shortcut, press the 'X' at the right edge of that box.
Keymou can be run as a traditional application, as a menu bar icon, or in a completely invisible "faceless" mode. For help on switching between these modes, read about the Advanced settings.
Getting Started
Keymou works by defining any number of actions (which can be executed via either the keyboard or Keymou's menu when used in menu bar mode) that will affect the cursor. The easiest way to get started with Keymou is to use its predefined actions, just to see what it can do:
Move the cursor: Hold down Shift and Control, then press one of the four arrow keys to move the cursor in the direction specified by that arrow. The cursor will start moving one pixel at a time, but will accelerate if you hold down the arrow key. Release the arrow key, and the cursor will stop moving.
Move the cursor by dividing the screen: Hold down Shift and Control, then press Tab (you can then release all three keys). A crosshair will appear onscreen; press the arrow keys to move the mouse in the specified direction by 50% of the available width; continue to press the arrow keys to narrow in on your target, then press Return to both move the mouse to the chosen location and to send a mouse click to that location.
Scroll: Press and hold Shift and Option, then press and hold the Up or Down arrow key to scroll in that direction by one pixel at a time. Continue to hold the arrow key down, and scrolling will accelerate in the chosen direction. Release all keys to stop scrolling.
Click and Right-Click: Press and hold Shift and Control, then press Return to send a mouse click to the current pointer's location. Use Shift and Option and Return to send a right-click instead.
A comment on nomenclature… What do you call it when you press the second mouse button (second tap zone?) on a Mac input device? Apple calls them 'secondary clicks' or 'secondary taps.' They can also be called Control-clicks (as that's how you simulate one on a one-button mouse) or right-clicks (as that's where the second button lives on a traditional mouse).
To keep things consistent in the help, we've chosen to refer to the second mouse button as the right button. Hence, if you see "right-clicks" in this text, know that we mean "a click (or tap) on the input device's second button."
Tips on Using Help
Our help system is designed to be easy to use. The top area of the window contains page navigation buttons on the left, and a magnifying glass icon (that will open a search box) on the right. If you find the font size too small, you can increase it by pressing ⌘=; ⌘- will reduce the size.
We use some standard conventions for certain bits of text throughout our help system:
These sections of text contain additional explanatory material that's related to the topic being discussed, but may go into more detail or not quite fit in the regular flow, so we set it apart with a visual call-out.
These sections of text contain tips, shortcuts, hidden features, or other similar "goodies" to help you get the most out of the app.
This is text we really want you to read—generally, something that's very important relative to your use of the app. If you're just skimming the help files, don't skim these notes—please read them.
When we reference items in the menu, we highlight each menu item's name, and separate them with an arrow, like this:
→ →When we reference a setting in Settings, it'll be called out like this: A user-settable setting
Keys you type are called out: ⌘⌃4
