I was writing "install tib" to disp the RC10. I had typed 'ins', and I pressed 'ON'. The line has been completed with "tall tall" (twice, with a space between the 2 "tall". It's not the first time I get something like that with auto-completion. I'll try to do a test case after the transfert. It doesn't seem to be always reproductible.

edit -> I still got that typing "fflash": "ffl" [on] "ash ash"

ok: This behavior seems to appear when you type [on] twice or more during completion.
