Why does this macro work in some apps but not in others?

[0x7145]

The following macro is supposed to delete the line where the cursor is positioned:

(macro (unmod end) 5 (unmod lsft home) 5 (unmod lsft home bspc) 5 (unmod bspc))

It works in web browsers and in VSCode, but not in Gedit or LibreOffice Writer. In those apps, the cursor is moved to the beginning of the line instead of deleting the whole line. Does anyone have any idea why it isn't working everywhere? I am running Kanata 1.8.1, and I tested everything with Fedora 37.

Here's the full configuration file:

(defcfg
   process-unmapped-keys yes
)

(defsrc
   tab
)

(deflayer base
   (macro (unmod end) 5 (unmod lsft home) 5 (unmod lsft home bspc) 5 (unmod bspc))
)

Thanks in advance

Likely the applications aren't successfully dealing with the rapidity of certain events. This is common in Linux unfortunately.

Maybe try this; you should hold the key until macro completion to ensure unmod stays active. Also it will unfortunately completely release lsft.

(defvar d 5) ;; delay value
...
   (multi (unmod (lalt ralt lmet rmet rsft lctl rctl) nop0)
          (release-key lsft)
          (macro $d end $d S-($d home) S-($d home $d bspc) $d bspc))

bsps twice like above causes trouble on empty lines (windows) ; maybe

(multi (unmod (lalt ralt lmet rmet rsft lctl rctl) nop0)
          (release-key lsft)
          (macro 5 end 5 S-(5 home) 5 spc 5 bspc 5 bspc)
        )

Finally, I ended up using the following action based on your suggestions:

(multi
   (release-key lctl)
   (release-key lsft)
   (macro end 5 S-(5 home) 5 S-(5 home) 5 bspc 5 bspc)
)

jtroo's suggestion didn’t solve the problem, and gerhard-h’s was missing the second S-(5 home), which is needed to remove indentation in programs like VSCode.

To be honest, I don’t know why it works with multi. I also don’t understand why S-(5 home) works, but S-home doesn’t. Could you explain the logic behind this?

Additionally, I noticed that it works fine without (unmod (lalt ralt lmet rmet rsft lctl rctl) nop0). What was the reasoning behind adding it? From the documentation, I gathered that nop0 is a "no operation" key, so I don’t see its purpose in this context.

Thanks again.

I ended up with ...(macro end 5 S-(5 home) 5 S-(5 home) 5 spc 5 bspc 5 del)...
del is for the first line edge case and spc for the empty line case

(unmod (lalt ralt lmet rmet rsft lctl rctl) nop0) seems like a fancy way to release all modifiers, but if ctI is really hold, shouldn't it be reactivated?

S-(5 home) means 5ms pause after shift and before home
