输入法 fcitx5
安装：
fcitx5-im
fcitx5-chinese-addons
fcitx5-breeze
Vim
自动切换输入法（参考 VIM输入法切换，不使用插件 - No Wander）：
分别在中文和英文输入状态下，执行 fcitx5-remote -n 得到此时的 input method name，我这里得到的结果分别是 keyboard-us 和 pinyin。
退出插入模式时，先保存当前输入法状态，再切换到英文输入法；
进入插入模式时，若之前保存的输入法状态为中文，则切换到中文。
let fcitx5state=system("fcitx5-remote")
autocmd VimEnter * :silent call system("fcitx5-remote -s keyboard-us")
autocmd InsertLeave * :silent let fcitx5state=system("fcitx5-remote -n") | silent call system("fcitx5-remote -s keyboard-us")
autocmd InsertEnter * :silent if fcitx5state == "pinyin\n" | call system("fcitx5-remote -s pinyin") | endif将 Tab 显示为 🡢：
set list
set listchars=tab:🡢\ ,extends:>,precedes:<两格缩进：
set tabstop=2 shiftwidth=2 expandtab使用 :Q 退出插入模式（因为常常按 Q 的时候忘了松开 Shift）：
:command Q qVSCode
Linux 键盘重映射不生效（参考 Keyboard mappings with setxkbmap on Linux not working）：
往 VSCode 设置里添加 "keyboard.dispatch": "keyCode"，然后重启 VSCode。

Replace GTK+ file dialog with alternative
touchpad - Precise scrolling in Firefox?
Solution: Add MOZ_USE_XINPUT2=1 to /etc/environment.
Stuck tooltips never disappear on Linux when switching to another app, until I switch to Firefox tab and hover the source of the tooltip
Solution: Add MOZ_GTK_TITLEBAR_DECORATION=system to /etc/environment.
声音
Output audio to multiple headphones at the same time
pactl load-module module-combine-sink sink_name=my-combine-sink sinks=node1,node2,node3,...Maybe outdated.
问题：Firefox 停止播放视频后（包括暂停一段时间再播放），所有系统音频停止工作（听不到声音，但声卡设备状态均正常），重启 wireplumber 才能恢复。
解决：https://www.reddit.com/r/archlinux/comments/umxi53/comment/i84prb9
Copy
/usr/share/wireplumber/main.lua.d/50-alsa-config.luainto/etc/wireplumber/main.lua.d/and find the["session.suspend-timeout-seconds"]and set it to 0. Restart wireplumber.
KDE kwin
No shadows around some windows in kde 5.7
Affected applications: some electron apps (linuxqq, clash-for-windows), wine apps (deepin-wine-wechat).
It's a result of something called "client side decorations".
Applications can tell Kwin "I want to draw my own decorations". Since shadows are usually part of the decoration the application would also need to draw the shadow, but sadly CSD applications don't do this.
If you are feeling committed you can manually add Kwin rules to force-draw a decoration without a titlebar (giving them shadows).
Solution:
In [ System settings ] -> [ Window management ] -> [ Window rules ] -> [ Appearance & Fixes ] , set [ No titlebar ] and frame to No.
或者：Alt + F3，更多操作，配置特殊应用程序设置，将「无标题栏和边框」设为「否」。
In [ System settings ] -> [ Application Style ] -> [ Window decoration ] -> [ Breeze theme setting ] -> [ Window specific overrides ], Set [ border size ] to No border size and set [ Hide Window title bar ] to yes.
