I have a macro for that purpose,
it fetches the line number via the Offset command in Viewer.

; call Offset to load Current Line Number into CLP:
; (does nothing to CLP: if Line mode Off)
o,CTRL_INS,ESC,

; in Execute window, start Notepad2 for current file
; with current line number as line offset (&col n for cursor visibility)
; and wait until it closes
x,CTRL_BKSP,@Notepad2.exe /g ,SH_INS,COMMA,1 ,TAB,RET,

; back to Viewer, Refresh to show modifications (if any)
ESC,F3,

You only have to replace the above /g by your editor's syntax.
BTW, TAB in eXecute echoes (fills in) the current filename.
