Down tube shifters
What is the highest number of gears that that an indexed down tube shifter will handle?

It depends on the specific shifter's cable pull. I had suntour power ratchets (awesome) on a vintage frame into which I stuffed a 9 speed cassette. The shifters did not pull enough cable length to cover the entire cassette, which meant adjusting out either the top or bottom cog.
Later model DT shifters - anything circa post-freewheel - will cover up to 11.
Dia-compe and Rivendell make vintage style DT shifters with outstanding fit and finish, though for the price you could score Dura Ace.

Worth noting: Shimano DuraAce downtube shifters in the 10- and 11-speed flavors do not swap over to friction shifting, they are index shifting only.

For me DT is limited by my skill level, 9 cogs. I just struggle with 10 and can not imagine trying 11.

Yep, a little comprehension deficiency, maybe.

14, a Rohloff grip shifter can also be mounted sticking out from the side of the Downtube.
not the most convenient location , but it is an option. .. just takes a 22.2-7/8" tube being added..
by the same method a NuVinci CVR hub has an infinite number of "speeds" with in its range of ratios..

I'm looking for a socket wrench and you want to tell me the value of a hand wrench. Don't think that I've forgotten about the hand wrench, but I've graduated to socket wrenches. Hope to see you guys in the Fall! Haha

However, a successful analogy would have been to use ratcheting and non ratcheting box wrenches.

All friction for front shifting as far as I know, no index option, will still work for double or triple front chainring setups.
I only mentioned the friction thing because in the past, DT and Bar End shifters were usually referenced in the same context as being simpler and less fragile than brake/shifter setups. Especially where touring is concerned, the ability to convert to friction shifting was seen as a benefit to such shifters, in the event of some emergency or if indexing got out of whack for some non-adjustable reason.
And so I commented about friction shifting, even though the OP specifically queried about index shifting. It might answer someone's unasked question, it's also a data point regarding the features of Shimano 10 and 11 speed DT indexing shifters being discussed here.
For those worrying about reading comprehension, I even prefaced the information I shared with "Worth noting:", a modifier very distinct from something more along the lines of, "Critical information regarding the OP!!!", or no modifier at all, which might imply that it directly answers the OP. Truly, said modifier could rather be read as, "Tangential but still somewhat pertinent to the OP" by those with any kind of nuanced reading comprehension, rather than the bludgeon of grammar/thread discipline Nazism displayed here.
