When I press ctrl-enter, I get the following keystroke event(Captured by xev). [...]

In the future please post the output of keyd -m, it is much more concise. It would also help if you could only post the relevant portion of the config.

As you can see, keyd sends 4 additional control_l and 2 shift_l

To summarize, the problematic portion of your config is equivalent to:

[customControl:C]
enter = macro(esc [18;6~)

and the output is:

Control_L down
Control_L up
Escape down
Escape up
bracketleft down
bracketleft up
1 down
1 up
8 down
8 up
semicolon down
semicolon up
6 down
6 up
Shift_L down
asciitilde down
asciitilde up
Shift_L up
Control_L down
Control_L up

The output is precisely what you should expect. I'm not sure what the 'additional shift' you're referring to is. Your macro contains ~ which necessarily produces the only shift key in the output. The control down/up events are present because you have bound the macro within a control layer, they should not affect the output.

I think part of your problem might stem from some misapprehensions about terminal input. ANSI sequences need to be written to the TTY. Input from your keyboard is generated by your terminal emulator as output from the TTY. You can't directly input special characters from your keyboard and expect the terminal to act on them. If you want an escaped statement suitable for use in things like printf then you probably want something like macro(\\033[31m) instead.

1. For example, this part of my configuration

   
   [main]
   leftshift = layer(leftshift{alacritty})

[leftshift{alacritty}:S] enter = macro(esc [17;5~)

2. When I press `shift-enter`, the event I detect is this, but I think the first line of `leftshift up` and the second line of `leftshift down` should not exist

leftshift down leftshift up esc down esc up [ down [ up 1 down 1 up 7 down 7 up ; down ; up 5 down 5 up leftshift down down up leftshift up

[rvaiya]

:S makes leftshift{alacritty} (incidentally you really should be using keyd-application-mapper) behave like shift. This means as soon as you press it shift down is emitted. It is a feature (not a bug). It should not have any effect on what you are trying to achieve in this instance.

I am using fcitx input method and bound shift to activate/disable it, the first and second events are detected by fcitx, so it is always activated or disabled every time I press shift-enter.

I think I may do some configuration in awesome wm, use different layout for different application by keyd ipc, not that keyd-application-mapper is bad, I just want to run as few things as possible, my computer performance is relatively low

1. I found that my composite layer configuration is also not working properly, for example, the following configuration

   [capslock{alacritty}+alt]
   h = macro(esc [1;3S)

2. When I press capslock+alt+h, I get the following event,which esc [1;3S become esc [1;4R,And there are two more events leftalt down and leftalt up

   
   leftalt down
   esc down
   esc up
   [ down
   [ up
   1 down
   1 up
   ; down
   ; up
   4 down
   4 up
   leftshift down
   r down
   r up
   leftshift up
   leftalt up

Then there is an inherent conflict in your bindings. You either want to avoid :S or (better) remap your fcitx key and then use overload within keyd to remap your left shift key to produce it on tap.

I think I may do some configuration in awesome wm, use different layout for different application by keyd ipc, not that keyd-application-mapper is bad, I just want to run as few things as possible, my computer performance is relatively low

Unless you are trying to avoid installing python, you are better off using the shipped option. The script is interrupt driven and spends most of its time waiting for X events (like awesome), using the awesome's IPC functionality doesn't avoid this (it just adds another socket between you and the X server).

When I press capslock+alt+h, I get the following event,which esc [1;3S

That is the expected output given your config. Please reread the man page (hint: you've rebound leftalt).

I am going to close this for now, since it involves several different issues and is not a bug.
