Still broken in Sublime 3.
When you type a letter, say 'f' and a completion popup appears
it then does't matter if "tab_completion" is false or true - pressing TAB will commit currently selected autocompletion word which might be or might not be a snippet
. The documentation says that setting tab_completion to false should only complete snippets. This is not the case. If the last time you completed 'f' with a snippet - it will complete snippet the next time, if it was a word - it will complete a word. And 'tab_completion' option has absolutely no effect on this behaviour.
if tab_completion is set to false everyone expects that only pressing ENTER will complete from completion popup. Pressing TAB should only trigger matching snippets or insert tab symbol. This is not the case, please fix it.
Please have a look at the following posts mentioning the same problem:http://sublimetext.userecho.com/topic/8 ... -reindent/http://sublimetext.userecho.com/topic/9 ... n-its-own/viewtopic.php?f=2&t=11434&start=0
