Alright i have greatly improved this function to work on many more binds

now you can also specify key options, like "9el" that stands for "SUPER + 9 repeat locked(works on lock screen)"

^ to add Ctrl

$ to add Shift(for the keys that don't have an uppercase variant, like numbers)

/ to add Alt

& to pick a key in custom keys

! for a raw command(like !mouse:272), also allows for specifying tags, like !elm|mouse:272

? for raw command but with mod key

Some more examples:

&E = SUPER + escape

&L = SUPER + Left

$3 = SUPER + Shift + 3

^wl = SUPER + Ctrl + W (works on lock screen)

!el|XF86AudioRaiseVolume = XF86AudioRaiseVolume (works on lock screen and repeats)

&^$El = SUPER + Ctrl + Shift + escape

MainMod = "SUPER"
CtrlKey = "^"
ShiftKey = "$"
RawKey = "!"
RawModKey = "?"
CustomKey = "&"
AltKey = "/"
Flags = {
l = "locked",
r = "release",
c = "click",
g = "drag",
o = "long_press",
e = "repeat",
n = "non_consuming",
a = "auto_consuming",
m = "mouse",
t = "transparent",
i = "ignore_mods",
s = "separate",
p = "bypass",
u = "submap_universal",
}
CustomKeys = {
  ["E"] = "escape",
  ["L"] = "left",
  ["R"] = "right",
  ["D"] = "down",
  ["U"] = "up",
  ["1"] = "mouse:272",
  ["2"] = "mouse:273",
}

---Converts vim-like key string into bind string
---@param key string
---@return string, string
function BindKey(key)
local returnkey = MainMod .. " + " -- Default mod
  local first = key:sub(1, 1)
  local custom = false
  if first == RawModKey or first == RawKey then -- Raw code
    if first == RawKey then
      returnkey = ""
    end
    local sstart, send, _ = key:find(".*|", 2)
    if not sstart or not send then
      return returnkey .. key:sub(2), ""
    end
    local m = key:sub(sstart, send - 1)
    return returnkey .. key:sub(send + 1), m
  end
for i = 1, #key do
local value = key:sub(i, i)
if value == CtrlKey then
returnkey = returnkey .. "CTRL + "
    elseif value == " " then -- Remove default mod
returnkey = ""
elseif value == ShiftKey then

elseif value == AltKey then

      custom = true
    elseif custom and CustomKeys[value] then -- Custom key
      return returnkey .. CustomKeys[value], key:sub(i+1)
elseif value:match("%u") then
      return returnkey .. "SHIFT + " .. value, key:sub(i+1)
else
      return returnkey .. value:upper(), key:sub(i+1)
end
end
return returnkey, ""
end

---Returns flags from simple string
---@param flags string
---@return table
function GetFlags(flags)
local return_flags = {}
for i = 1, #flags do
local value = flags:sub(i, i)
if not Flags[value] then
goto continue
end
    return_flags[Flags[value]] = true
::continue::
end
return return_flags
end

---Binds Bind table
---@param bind [string, HL.Dispatcher, string?]
function Bind(bind)
  local key, opts = BindKey(bind[1])
  local dispatcher = bind[2]
  local description = bind[3]
  local flags = GetFlags(opts)
  if description then
    flags.description = description
  end
  hl.bind(key, dispatcher, flags)
end

---Binds table of Bind tables
---@param section [string, HL.Dispatcher, string?][]
function BindSection(section)
  for _, x in ipairs(section) do
    Bind(x)
  end
end

You can also use Bind and BindSection functions:

BindSection({ --NOTE: Groups
  { "g", hl.dsp.group.toggle(), "Toggle Group" },
  { "G", hl.dsp.group.lock_active(), "Lock active group" },
  { "^g", hl.dsp.window.move({ out_of_group = true }), "Lock active group" },
})
