AHK: Select & append words - autohotkey

Question

I would like to select non-adjacent words while holding down some shortcut key, append them (space-separated) to one single string and put the final, appended string into the clipboard.
Something like:
{Control_down}::
OnDoubleClick{ my_appended_string += Str(current_text_selection) }
{Control_up}
Clipboard := my_appended_string
return
Just so it works :-)
Can you help?

; LCtrl+DoubleClick on words in text
<^LButton Up::
if (A_PriorHotKey = A_ThisHotKey and A_TimeSincePriorHotkey < DllCall("GetDoubleClickTime"))
{
; KeyWait, LCtrl ; after releasing LCtrl
clip_old := clipboard ; save the clipboard to the variable clip_old (as text))
clipboard := "" ; empty the clipboard (start off empty to allow ClipWait to detect when the text has arrived)
Click 2 ; select a word by doubleclick
Send, {Ctrl down}c{Ctrl up} ; copy the selected word
ClipWait 1 ; wait for the clipboard to contain data.
If (!ErrorLevel) ; If NOT ErrorLevel ClipWait found data on the clipboard
{
clip_new := clip_old A_Space clipboard ; append the new copied text to clip_old
clipboard := clip_new
}
else
{
MsgBox, No text copied
clipboard := clip_old
}
ToolTip, %clipboard%
Sleep, 1000
ToolTip
}
Return
EDIT:
Try also this
; Press F1 after putting the mouse pointer over the word to copy
F1 Up::
clip_old := clipboard ; save the clipboard to the variable clip_old (as text))
clipboard := "" ; empty the clipboard (start off empty to allow ClipWait to detect when the text has arrived)
Click ; on the word under the mouse pointer
Send, {Ctrl Down}{Left}{Ctrl Up}{Ctrl Down}{Shift Down}{Right}{Shift Up}{Ctrl Up} ; select the word
Sleep, 300
Send, {Ctrl down}c{Ctrl up} ; copy the selected word
ClipWait 1 ; wait for the clipboard to contain data.
If (!ErrorLevel) ; If NOT ErrorLevel ClipWait found data on the clipboard
{
clipboard := Trim(clipboard) ; remove leading/trailing spaces and tabs
clip_new := clip_old A_Space clipboard ; append the new copied text to clip_old
clipboard := clip_new
}
else
{
MsgBox, No text copied
clipboard := clip_old
}
ToolTip, %clipboard%
Sleep, 1000
ToolTip
Return
