add callStepGroup here, may be more intuitive to use.

Try don't use a too small result time/scale, the overhead may turn the call sequence not as expected.

Code:

local function callnext(n,f,...) -- make local so not mixed with may be another version of callnext
  local pk,upk,t,p = table.pack,table.unpack,createTimer()
  if type(n)~='number'then n,f,p=1,n,pk(f,...)else p = pk(...)end
  t.Interval,t.OnTimer = n,function(tm)
    tm.Destroy()
    pcall(f,upk(p))
  end
  return t
end

function callstep(n)
  assert(type(n)=='number' and n>0,"Input not a positive number: "..tostring(n))
  local pk,upk,p = table.pack,table.unpack,{}
  local function collect(f,...)
    if f == nil then
      for i=1,#p do if p[i][1] then callnext(1+(i-1)*n,p[i][1],upk(p[i],2)) end end
    else
      p[1+#p]= pk(f,...)
      return collect
    end
  end
  return collect
end


local msev = mouse_event
local function mclick(down,up,int)
  local down,up,int = down,up,int or 35
  return function()
    local t = createTimer(),msev(down)
    t.Interval,t.OnTimer = int,function(tm)tm.Destroy();msev(up)end
  end
end
local mouse2func = {
 ['+m0']= {msev,2},['-m0']= {msev,4},['^m0']={mclick(2,4)},
 ['+m1']= {msev,8},['-m1']= {msev,16},['^m1']={mclick(8,16)},
 ['+m2']= {msev,32},['-m2']= {msev,64},['^m2']={mclick(32,64)}
}
local key2func = {['^']=doKeyPress,['+']=keyDown,['-']=keyUp}
function callStepGroup(scale)
  assert(type(scale)=='number' and scale>0,"Scale is not positive number: "..tostring(scale))
  local pk,upk,fmt,int,p = table.pack,table.unpack,string.format,math.floor,{}
  local function collect(maintime,...)
    if maintime == nil then
      local callset,mainacc,subacc = {},1
      for i=1,#p do
        local spec = p[i]
-- spec in format :  maintime, { func1, ... }, subtime1, { func2, ... }, subtime2,...{ funcN, ...}
        local maintime = spec[1]
        if maintime == false then break end
        assert(type(maintime)=='number',
          fmt("maintime in step %d is not number: %s",i,tostring(maintime)))
        mainacc = int(mainacc + maintime * scale)
        subacc = mainacc
        for j=2,#spec,2 do
          local group = spec[j] -- in format { func, ... }
          if group == false then break end
          if type(group)=='string' and group:match"^[-+^]%w+$" then --key-related shortcut
            local mev = mouse2func[group:lower()]
            if not mev then
              local func, key = group:match"([-+^])(%w+)"
              func = key2func[func]
              key = _G["VK_"..key:upper()]
              group = {func,key}
            else
              group = mev
            end
          end
          assert(type(group)=='table',
            fmt("%d(th) group in step %d is not table: %s",j,i,tostring(group)))
          callset[1+#callset] = pk(subacc,upk(group))
          if j<#spec then -- if not last subgroup
            local subtime = spec[j+1]
            if subtime == false then break end
            assert(type(subtime)=='number',
              fmt("%d(th) subtime in step %d is not number: %s",j,i,tostring(subtime)))
            subacc = int(mainacc + subtime * scale - 1)
          end
        end-- j
      end--i
      return function(extraScale)
        if type(extraScale)=='number' and extraScale~=1 then
          for i=1,#callset do callnext(callset[i][1]*extraScale,upk(callset[i],2))end -- fire
        else
          for i=1,#callset do callnext(upk(callset[i]))end -- fire
        end
      end
    else
      p[1+#p]= pk(maintime,...)
      return collect
    end
  end
  return collect
end

-- test callStepGroup

local preGeneratedCallSet =   callStepGroup(10) -- scale
    (  0,{keyDown,VK_A},25,{keyUp,VK_A}) -- first number is relative to whole sequence, after scale multiplied
    ( 25,{keyDown,VK_W},25,{keyUp,VK_W}) -- subsequence number is time relative to the parent group, after scale multiplied
    ( 50,{keyDown,VK_D},25,{keyUp,VK_D})
    ( 75,{keyDown,VK_S},25,{keyUp,VK_S})
    (100,{keyDown,VK_LSHIFT},100,{keyUp,VK_LSHIFT}) -- sprint?
    (100,"+A",25,"-A") -- shortcuts
    (125,"+W",25,"-W")
    (150,"+D",25,"-D")
    (175,"+S",25,"-S")
() -- generate the callset here
-- not fire yet, so that the callset is generated once,
   and can be execute elsewhere any time.


local hk = createHotkey(function()-- the function to do on hotkey

  preGeneratedCallSet(2) -- fire now with an extra time scaling

end,
VK_NUMPAD0)

-- or

local hk = createHotkey(preGeneratedCallSet,VK_NUMPAD0) -- better if no extra scaling for lesser one function wrap

callnext(20000,function()
  hk.Destroy()
  print("destroying")
end)


ADDED:
added shortcut to 3 key-related function call: doKeyPress ('^'), keyDown ('+'), keyUp ('-'). eg.
{keyDown,VK_D} -- a table, can be shortcut as
"+D" -- a string, see test example.

ADDED:
add mouse click too.
m0 is left mouse button, m1 is right and m2 is middle.
"+m0" means press left mouse button down,
"-m1" means release right mouse button (up),
"^m0", simulate a left mouse button click, it is made by a sequence of

1.left mouse button down,
2.wait ~35 ms (there is overhead)
3.left mouse button up,

There should be no other left mouse event send during the interval, should assume at least 40ms in between I guess.
