i'm working on  a picture, and

 

              -- Add a new layer

              -- paint it all white

              -- put the layer underneath

              -- Control-M to merge

 

----------  is there a shortcut that combines these 4 steps ?

It would be trivial to create a plugin to do this.

    return blendNormal;

No, because such a shortcut would be specific to your particular way of doing this.


So, either use @BoltBait's code, or this sequence of shortcut keys:

- Add a new layer                 Ctrl+Shift+N

 

- Move layer down               Alt+L+O

 

- Fill it with Pri/Sec colour   Ctrl+A  then  Shift+Backspace to fill selection with the Secondary colour (the paint.net default is white)
                                                               or  Backspace to fill selection with the Primary colour

 

- Merge layer above down  Alt+PgUp  then Ctrl+M

 
 

This sequence can be activated by a single shortcut Ctrl+Shift+Alt+M for Secondary colour (or Ctrl+Alt+M for Primary colour) using AutoHotkey

#Requires AutoHotkey v2
#SingleInstance Force

; Ctrl+Shift+Alt+M to place the current layer over the Secondary colour & merge
; Ctrl+Alt+M       to place the current layer over the Primary colour & merge

#HotIf WinActive("ahk_exe paintdotnet.exe")
^+!m::   
^!m::   
{
    Send "^+n"   ; New layer
    Send "!lo"   ; Move layer down
    Send "^a"    ; Select all

    ; Did the pressed hotkey include Shift?
    if InStr(A_ThisHotkey, "+")
        Send "+{Backspace}"    ; Fill with Secondary colour
    else
        Send "{Backspace}"     ; Fill with Primary colour

    Send "!{PgUp}"   ; Go to layer above
    Send "^m"        ; Merge down
}
