ubuntu点击dock图标最小化窗口

敬请参考：
https://zhuanlan.zhihu.com/p/585280693

设置左键单击按钮功能

gsettings set org.gnome.shell.extensions.dash-to-dock click-action minimize-or-previews

minimize-or-previews是：
多窗口：显示预览
单窗口：最小化

还有其他选项，查看方式：

gsettings range org.gnome.shell.extensions.dash-to-dock click-action

'skip'
'minimize'
'launch'
'cycle-windows'
'minimize-or-overview'
'previews'
'minimize-or-previews'
'focus-or-previews'
'focus-minimize-or-previews'
'quit'

minimize是点击最小化/最大化，如果有多个窗口，会全部最小化/最大化。
focus-or-previews：如果只有一个窗口，则置于前台；如果有多个窗口，则置于前台或显示多窗口预览
focus-minimize-or-previews：一个程序启动了多个窗口时：focus-or-previews；只有一个窗口时：minimize

个人推荐设置

感觉这些都不是很中意，尤其是多窗口最小化和预览无法兼顾，所以本人推荐设置：
shift + click: previews
click: minimize
这样左键是最小化，比较符合windows的操作逻辑，想多窗口选择的时候用shift-click

查询和click相关的设置项：

gsettings list-recursively  org.gnome.shell.extensions.dash-to-dock | grep click

org.gnome.shell.extensions.dash-to-dock click-action 'minimize-or-previews'
org.gnome.shell.extensions.dash-to-dock shift-click-action 'launch'
org.gnome.shell.extensions.dash-to-dock shift-middle-click-action 'minimize'
org.gnome.shell.extensions.dash-to-dock middle-click-action 'launch'

设置“左键单击”最小化，“shift+左键单击”查看多窗口预览

gsettings set org.gnome.shell.extensions.dash-to-dock click-action minimize
gsettings set org.gnome.shell.extensions.dash-to-dock shift-click-action previews
