使用 xcape 和 xkb 将普通键用作修饰键

为了在适当的情况下进行Spacebar操作Ctrl,目前的 GitHub 页面xcape说明如下:

# Map an unused modifier's keysym to the spacebar's keycode and make it a
# control modifier. It needs to be an existing key so that emacs won't
# spazz out when you press it. Hyper_L is a good candidate.
spare_modifier="Hyper_L"
xmodmap -e "keycode 65 = $spare_modifier"
xmodmap -e "remove mod4 = $spare_modifier" # hyper_l is mod4 by default
xmodmap -e "add Control = $spare_modifier"

# Map space to an unused keycode (to keep it around for xcape to
# use).
xmodmap -e "keycode any = space"

# Finally use xcape to cause the space bar to generate a space when tapped.
xcape -e "$spare_modifier=space"

如何用xkb而不是实现这一目标xmodmap

答案1

Hyper_R代替Hyper_L,它是这样的:

内容~/.config/xkb/keycodes/my-keycodes

xkb_keycodes "xcape-special" {
    <HYPR> =  65;
    <SPCE> = 207;
};

注意:是我的机器上加载的键码表中207(虚拟)键的默认键码。Hyper_R

内容~/.config/xkb/symbols/my-symbols

xkb_symbols "xcape-special" {
    key <HYPR>  { [ Hyper_R ] };
    modifier_map Control { <HYPR> };
};

摘录自~/.xinitrc

XKB_DIR="$HOME/.config/xkb"
XKB_SYMBOL_FILE="my-symbols"
XKB_KEYCODE_FILE="my-keycodes"

setxkbmap -layout "us+$XKB_SYMBOL_FILE(xcape-special)" \
    -keycodes "evdev+$XKB_KEYCODE_FILE(xcape-special)" \
    -option "" -print \
    | xkbcomp -I"$XKB_DIR" - "${DISPLAY%%.*}" >/dev/null 2>&1

xcape -e "Hyper_R=space"

这不是唯一的配置方法xkb。配置可能可以通过一次调用从单个文件加载xkbcomp。的子目录~/.config/xkb/仅遵循 的结构/usr/share/X11/xkb/。这... -print | xkbcomp ...部分有点复杂但很灵活。目前我无法尝试更简单的设置。
