I'm using 12.0.0 for Microsoft Windows (64-bit), and the autocomplete feature is a bit of a mess. In previous versions I used to be able to type Ta and hit the tab key, and this was autocompleted into Table, an extremely useful tool. But now the ordering of the autocomplete suggestions is rather bad, for the first suggestion is TableForm instead of Table, and I see myself going back to fix things all the time. Is there any way to set up a preferred set of commands for the autocomplete feature? If this could be done automatically (say, order by frequency of usage) that'd be great, but even a manual choice of priority would be better than the current ordering.

I've just tried your exact example on Win10-64 and MMA 12 and Ta + tab in fact autocompletes to Table in my system. You may try deleting your autocompletion history.

You can find that here:

FileNameJoin[{
  $UserBaseDirectory, 
  "SystemFiles\\FrontEnd\\SystemResources\\FunctionalFrequency\\AutocompletionHistory.m"}
]

    $\begingroup$ @AccidentalFourierTransform Yes, they should be! I fixed it; thank you for pointing that out. $\endgroup$

    $\begingroup$ An OS independent way to create the file name is to use: FileNameJoin[{ $UserBaseDirectory, "SystemFiles", "FrontEnd", "SystemResources", "FunctionalFrequency", "AutocompletionHistory.m"} ] $\endgroup$

  • $\begingroup$ Thanks. Unfortunaltely, this didn't work. BTW, could you try with Cl? This used to autocomplete into Clear, but now it becomes CloudDeploy! (I've never used this function, not even sure what it does...) $\endgroup$ Dec 4, 2019 at 17:24
  • $\begingroup$ @AccidentalFourierTransform Cl autocompletes to ClearAll on my system; that makes sense to me, since I use ClearAll much more often than Clear. Indeed ClearAll appears in my AutocompletionHistory.m file associated with a higher value than Clear. I take that value to indicate priority. $\endgroup$

  • $\begingroup$ @MarcoB any indication as to if you can deliberately mark one suggestion high than the others, in order to brute-force a solution to this? $\endgroup$ Dec 5, 2019 at 5:17
