Trackpad gestures

Mouse_controls Mac Os X
Mac Os Catalina

For more information about these gestures, choose Apple menu  > System Preferences, then click Trackpad. You can turn a gesture off, change the type of gesture, and learn which gestures work with your Mac.

The figure below shows gesture sets available for managing windows in Windows (7, 8, or later) and Mac OS X (10.8 or later). Tip: Use Logitech Options to view available gesture sets and assign gestures to the middle button or to other mouse controls. Minecraft Java Edition (PC/Mac) Minecraft Java Edition (PC/Mac) is a version of the game that runs on a PC or Mac computer. Therefore, you would use your keyboard and mouse to navigate through the game. Here are the game controls to play Minecraft Java Edition (PC/Mac). The figure below shows gesture sets available for managing windows in Windows (7, 8, or later) and Mac OS X (10.8 or later). View and enable other gesture sets in Logitech Options. Tip: Use Logitech Options to view available gesture sets and assign gestures to the navigation button or to other mouse controls. This works well, but with a bug: the OS won't let me programmatically resize a window taller than one row. I can resize it large with the mouse, but not with AppleScript. With this code, I can first use AppleScript to create and position a window, and then use a command-line clicky-drag program to stretch the window to the size I want.

Trackpad gestures require a Magic Trackpad or built-in Multi-Touch trackpad. If your trackpad supports Force Touch, you can also Force click and get haptic feedback.

Secondary click (right-click)
Click the right side of the mouse.

Smart zoom
Double-tap with one finger to zoom in and back out of a webpage or PDF.

Mission Control
Double-tap with two fingers to open Mission Control.

Swipe between full-screen apps

Mouse keys is a feature of some graphical user interfaces that uses the keyboard (especially numeric keypad)as a pointing device (usually replacing a mouse). Its roots lie in the earliest days of visual editors when line and column navigation was controlled with arrow keys.Today, mouse keys usually refers to the numeric keypad layout standardized with the introduction of the X Window System in 1984.^[1]^[2]

Layout[edit]

X window system MouseKeys default numpad layout

key	action
Num Lock	With Alt-Shift Enable/Disable MouseKeys
8	cursor up
2	cursor down
6	cursor right
4	cursor left
7	cursor up and left
9	cursor up and right
3	cursor down and right
1	cursor down and left
/	select primary button
*	select modifier button
-	select alternate button
5	click selected button
+	double click selected button
0	depress selected button
.	release selected button
Enter	Enter Key

History[edit]

Historically, MouseKeys supported GUI programs when many terminals had no dedicated pointing device. As pointing devices became ubiquitous, the use of mouse keys narrowed to situations where a pointing device was missing, unusable, or inconvenient. Such situations may arise from the following:

precision requirements (e.g., technical drawing)
disabled user or ergonomics issues
environmental limits (e.g., vibration in car or plane)
broken/missing/unavailable equipment

MouseKeysAccel[edit]

X window system MouseKeysAccel trajectory

parameter	meaning
mk_delay	milliseconds between the initial key press and first repeated motion event
mk_interval	milliseconds between repeated motion events
mk_max_speed	steady speed (in action_delta units) applied each event
mk_time_to_max	number of events (count) accelerating to steady speed
mk_curve	ramp used to reach maximum pointer speed

The X Window System MouseKeysAccel control applies action (usually cursor movement) repeatedly while a direction key{1,2,3,4,6,7,8,9} remains depressed.^[3] When the key is depressed, an action_delta is immediately applied. If the key remains depressed, longer than mk_delay milliseconds, some action is applied every mk_interval milliseconds until the key is released. If the key remains depressed, after more than mk_time_to_max actions have been applied, action_delta magnified mk_max_speed times, is applied every mk_interval milliseconds.

The first mk_time_to_max actions increase smoothly according to an exponential.

$a c t i o n_d e l t a \times m k_m a x_s p e e d \times {(\frac{i}{m k_t i m e_t o_m a x})}^{\frac{1000 + m k_c u r v e}{1000}} {displaystyle mathrm {action_delta} times mathrm {mk_max_speed} times left({frac {i}{mathrm {mk_time_to_max} }}right)^{frac {1000+mathrm {mk_curve} }{1000}}}$

mk_curve	result
-1000	uniform speed, linearly increasing action
0	uniform acceleration, linearly increasing speed
1000	uniform jerk, linearly increasing acceleration

These five parameters are configurable.^[4]

Enabling[edit]

Under the X Window SystemsXorg and XFree86 used on Unix-like systems such as Linux, BSD, and AIX, MouseKeys (and MouseKeysAccel) is nominally (de)activated by Alt+Left Shift+Num Lock.^[5] MouseKeys without acceleration (also known as plot mode) is sometimes available with Shift+NumLock. This is independent of the Window Manager in use and may be overridden by a configuration file. The setxkbmap utility can be used to temporary enable mouse keys under Xorg:^[6]

setxkbmap -option keypad:pointerkeys

There are also various utilities to allow more precise control via user-configurable key bindings, such as xmousekeys and xdotool.

MouseKeys for Apple Inc's Mac OS X is enabled and configured via the Accessibility^[7] ([apple] → System Preferences → Accessibility → Mouse & Trackpad).

Microsoft changed the method of enabling between Windows 2000,^[8]Windows XP (added diagonal cursor movement and MouseKeysAccel),^[9] and Windows Vista.^[10]

Common usage[edit]

Replacing the mouse keys[edit]

Replacing the mouse keys by the numeric keypad is as follows:

Typing 5 (with the numeric keypad) is equivalent to clicking the selected button. By default, the selected button is the primary button (nominally under index finger, left button for most right-handed people and right button for most left-handed people). Typing - (with the numeric keypad) selects the alternate button (nominally under ring finger, right button for most right-handed people and left button for most left-handed people). Typing * (with the numeric keypad) selects the modifier button (nominally under the middle finger, middle button of a 3-button mouse). Typing / (with the numeric keypad) selects the primary button. The selection remains in effect until a different button is selected.

Assignment of left/middle/right button to primary/modifier/alternate, alternate/modifier/primary, or something else is settable by many means. Some mice have a switch, that swaps assignment of right and left keys. Many laptop bioses have a setting for mouse button assignment. Many window managers have a setting that permutes the assignment. Within the X Window System core protocol, permutation can be applied by xmodmap(1).
