See screenshot named as tooltip.png, which is shown in TeXstudio.

I tried `ivy' in Emacs, but it shows some shortcomings, as described below:

1. The incremental drop down menu only will be triggered when the
input character number greater than 3.
2. Some commands, say, `\href', will not be automatically completed at all.

But TeXstudio doesn't have all the above-mentioned disadvantages, see
screenshot named as autocompletin.png for more detailed info.
