In the command interpreter type: import readline readline.parse_and_bind('Control-tab: "import"')
Then type control-tab on the next line. readline should insert import. PyPy 2.7.9 (2.5.1+dfsg-1, Mar 27 2015, 19:45:43) doesn't.
There is an alternative syntax.
This doesn't work either. Note that CPython Python 2.7.9 (default, Mar 1 2015, 12:57:24)
has bugs over this also, but different ones.
readline.parse_and_bind(r'"\C-\t": "import"') in CPython does nothing. readline.parse_and_bind('Control-tab: "import"') works but if you then do readline.parse_and_bind('tab: "raise"')
both tab and control-tab will be set to insert "raise" by CPython. There seems to be no way to bind control-tab and tab to different things in CPython.
This bug was discovered by Steve D'Aprano in CPython 2.7. He will probably make a CPython bug report about it soon.
