Thank you very much!
By the way: sometimes I want to attach a screenshot to an email (working with Tunderbird/windows). So I am using this little autohotkey script, active only when the post capture dialog box is open and activated just by simply pressing the key "t":
#IfWinActive, ahk_class TPostCapture2Form
Send, c ;# copy file path
sleep, 500 ;# wait "another" half a second
Run, thunderbird.exe -compose "attachment='%clipboard%'"
Or e.g. this little helper script -- shorter than the button "Send to...":
;# key P: open the file directly in Photoshop
Run, "%path_photoshop%" "%clipboard%"
And so on
