Here is a trick to toggle system tray visibility in Awesome using keyboard shortcut. The reason to do that is pretty simple - it looks ugly in some themes. In my case I don't like two things about it:
- I didn't manage to make it transparent which is quite important since I am using transparent tasklist and widgets. I tried `wibox.widget.systray.opacity` property which doesn't work as well as setting an alpha channel for `beautiful.bg_systray`.
- Colors of the apps are very different from theme colors which makes systray look flashy and disturbing:
On the other hand not showing it at all will make interaction with some apps pretty difficult. So having a keyboard shortcut which toggles its visibility sounds like a good solution for the problems mentioned above.
To do it create a systray widget inside `awful.screen.connect_for_each_screen` function:
```lua
awful.screen.connect_for_each_screen(function(s)
...
s.systray = wibox.widget.systray()
s.systray.visible = false
...
```
Then add it to the the wibox: replace default `wibox.widget.systray()` by `s.systray` inside `s.mywibox:setup` method:
```lua
s.mywibox:setup {
...
s.mytasklist, -- Middle widget
{
...
s.systray
...
```
Almost done, the only thing left is a shortcut, I use `mod`{:.key} + `=`{:.key}:
```lua
awful.key({ modkey }, "=", function ()
awful.screen.focused().systray.visible = not awful.screen.focused().systray.visible
end, {description = "Toggle systray visibility", group = "custom"})
