Mouse, keyboard and Finder
Small switches that change how your mouse, trackpad, keyboard, Finder and Dock behave. Each one is off until you turn it on, and nothing of it runs while it's off.
Where to find them
They're on two Settings pages:
- Settings → Mouse & Scrolling: scrolling, the pointer, mouse buttons, the trackpad's middle click and key filtering.
- Settings → Finder & Apps: cut and paste in Finder, ⌘Q and ⌘W protection, and Dock clicks.
Turn a switch on and its options appear under it. You can also flip most of them from the Controls tab of the Menu Bar Panel. They need Saiki's Accessibility permission; Finder cut and paste also asks to control Finder the first time.
Scrolling
These change mouse wheels only. The trackpad keeps macOS's natural scrolling.
| Setting | What it does |
|---|---|
| Reverse the mouse wheel | The wheel scrolls the other way. |
| Reverse sideways scrolling | A mouse's sideways scrolling goes the other way. |
| Scroll sideways while holding a key | Hold only the chosen key and the wheel scrolls sideways. Key to hold: ⇧ Shift (the default), ⌥ Option, ⌃ Control or ⌘ Command. |
| Smooth scrolling | Each notch becomes a short, gentle glide instead of a jump. |
| Linear scrolling | Every notch scrolls the same distance, however fast you spin the wheel. Lines per notch: 1 to 10 (3 to start). |
Smooth scrolling has three options:
- Scrolling speed: how far one notch glides, from 20 to 100 pixels (40 to start).
- Response: higher follows the wheel sooner (65 % to start).
- Coast: higher keeps the start of each glide and slows only its landing (0 % to start).
The pointer
Mouse acceleration
Turn on Turn off mouse acceleration and mice move the pointer at one speed, however fast you move them. Trackpads aren't changed. When you turn it off again or quit Saiki, your own setting comes back, even if Saiki was force quit.
From the bar, type mouse acceleration and press ↵ on Mouse Acceleration to flip it. The row shows its state, "Off · mice move at one speed" or "On · macOS's acceleration".
Focus follows mouse
With Focus follows mouse on, the window under the pointer takes the keyboard after the pointer rests on it for a moment. Its options:
- Hover delay: how long the pointer rests before the window takes focus, from 100 ms to 3 seconds (250 ms to start).
- Bring the window to the front (on): it comes in front of the others too. Off, it gets the keyboard where it is.
- Wait for the pointer to stop (on, shown while the window isn't brought to the front): off, time over a window counts even while the pointer moves.
Mouse buttons
Side buttons
Side buttons go back and forward makes a mouse's Back and Forward buttons go back and forward in Finder, browsers and other apps that have those commands.
Button shortcuts
Turn on Shortcuts on extra mouse buttons, then choose Add Button Shortcut…: press the mouse button, then the keys it should press. The button then presses those keys, and the app under the pointer no longer gets the click. Each button you set has its own row: ↵ records new keys and ⌘⌫ removes it.
Spaces drag
Turn on Hold a button and drag to switch Spaces and choose the Button to hold (↵, then press it). Hold that button and drag left or right to move between Spaces, up for Mission Control or down for App Exposé. The Space follows your hand makes the Space move the way your hand does, like natural scrolling.
The drag uses the Mission Control keyboard shortcuts set in System Settings → Keyboard → Keyboard Shortcuts. If you've turned one of those off, that direction does nothing.
Click filter
A worn mouse button sometimes clicks twice when you press it once. Filter accidental double clicks drops a second click that comes too soon after a real one. Real clicks are never delayed. Filter window sets how soon counts as too soon, from 10 to 100 ms (25 ms to start).
Middle click
Three-finger click is a middle click: press the trackpad with three fingers and it works like a wheel click, to open a link in a new tab or close a tab. If you use three-finger drag, it takes four fingers instead. A light tap also clicks makes a light tap with 3 or 4 fingers, without pressing, count too; it's Off to start with, and sliding never counts.
Keyboard
A worn key sometimes types its letter twice. Filter duplicate key presses drops a second press of the same key that comes within a few milliseconds. Holding a key still repeats as usual.
- Filter window: how soon a second press is dropped, from 5 to 120 ms (5 ms to start).
- Add a Key… gives one key its own window: press the key, then press ↵ on its row to step through the windows. ⌘⌫ removes it.
Apps left alone
Each of these has its own list of apps it never touches: Scroll Direction, Smooth Scrolling, Linear Scrolling, Focus Follows Mouse, Side Buttons, Button Shortcuts and Middle Click. While the feature is on, its card has Leave an App Alone…; pick an app (or a program, such as a game) and the feature steps aside while you use it. Select an app in the list and press ⌘⌫ to take it off.
Finder
Cut and paste files
Turn on Cut and paste files in Finder. In Finder, select files and press ⌘X to cut them, then open another folder and press ⌘V to move them there. Text fields work as usual, so cutting text while you rename a file still cuts text.
- Show what's cut (on) shows a small card at the top of the screen listing the files you cut while Finder is in front. A move to another disk shows its progress there.
- Copying something else after you cut cancels the cut.
- A file whose name is taken in the new folder gets a number added, like "Report 2".
- Files only an administrator can move are moved by Finder, which asks for your password.
Paste an image as a file
Paste a copied image as a file (shown while cut and paste is on): copy an image, for example from a web page or a screenshot to the clipboard, then press ⌘V in a Finder window. Saiki saves it there as a PNG named like Pasted_Image_20261101_143005.png. Copied files paste as usual.
Rename with a shortcut
Rename in Finder with a shortcut makes a key run Finder's Rename on the selected file, as ↩ does. The key is F2 to start; select Rename keys and press ↵ to record others, or ⌘⌫ to go back to F2. It only acts while Finder is in front and you aren't typing in a text field.
Quit and close protection
Turn on Protect ⌘Q and a slip of the keys never quits an app. Protect ⌘W does the same for closing windows. Each has the same options:
| Option | What it does |
|---|---|
| How to confirm | Hold the shortcut (the default), Press twice, or Add a key. |
| Hold for | With Hold: how long to hold, from 500 ms to 2 seconds (800 ms to start). |
| Second press within | With Press twice: how soon the second press must come, from 300 ms to 1.5 seconds (600 ms to start). |
| Extra key | With Add a key: ⇧ Shift (the default), ⌥ Option or ⌃ Control. The bare shortcut does nothing. |
| Show a hint while ⌘Q is held | On to start: a small hint at the bottom of the screen says what to do, with a bar that fills as you hold. |
| Apps | Every app, Only these apps or Every app but these. The last two show a list with Add App…. |
Dock clicks
These change what happens when you click the Dock icon of the app you're already in. Clicks on other apps' icons work as usual.
- Click the Dock icon to minimize: minimizes its windows; click again to bring them back.
- Click the Dock icon to hide the app: hides it; click again to bring it back.
- Click the Dock icon to cycle windows: brings its next window forward, like ⌘`.
Turning them off
The switch at the top of Settings → Mouse & Scrolling or Settings → Finder & Apps turns off everything on that page at once. Off leaves nothing running, and anything Saiki changed, like mouse acceleration, goes back to how it was.
