Linux Mint: How To Configure How Alt-Tab works
Alt + Tab is a standard shortcut in many operating systems for switching between open windows. Linux Mint also supports this and allows you to configure the options a bit to your personal preferences. To configure Alt + Tab options in Linux Mint, press the Super key, type “Windows” and press Enter.
Set the Alt-Tab function
Tip : The “Super” key is the name many Linux distributions use to refer to the Windows key or the Apple “Command” key, avoiding any risk of trademark issues.
Press the Super key, type “Windows” and press Enter.
Once you are in the “Windows” options, switch to the “Alt” tab. Here, the first option configures how the window switcher preview works when you press and hold Alt while using Alt + Tab. There are a number of options, the two marked “(3D)” will require more graphics processing power. All options should be fine, even on integrated graphics. If you are using a Linux Mint virtual machine with software rendering, the 3D options may cause some stuttering.
You can change the appearance of the window list by holding Alt after pressing Alt + Tab.
Primary monitor options
“Show alt-tab switch on primary monitor instead of active” is used to force the preview of open windows to be displayed on the primary monitor instead of the monitor with the currently active window. “Move minimized windows to end of alt-tab” specifically moves windows that have been minimized to the end of the queue. This can be useful if you only want to switch between open windows. Alternatively, it can be annoying if you want to scroll through the latest windows.
“Alt-tab switcher display delay (milliseconds) allows you to choose how long you have to hold Alt after pressing Alt + Tab for the window switcher to appear. The default value of 100 milliseconds is pretty good, a little less. It becomes difficult to Alt + Tab to switch back to the last window without popping up. More than that means you have to wait longer than necessary.
“Show windows from all workspaces” is used to toggle whether you only want to be able to switch between windows in the current workspace. Or between all windows in all workspaces.
Tip : Switching to a window in another workspace automatically switches you to that workspace, not dragging the selected window to the current workspace.
You can also configure where the Alt + Tab switch appears, how quickly it appears, and whether it displays windows from all workspaces.
