Add existing tags to posts plugin

Hi,

I need to find a plugin to allow me to select tags from a drop down menu and add them to the post by clicking a button. I’ve got tones of tags and I simply can not write them all over again when I need to add some tags to my posts. It is also very difficult not to make a mistake and create new versions of an existing tag… This is what the Advanced Tag Entry used to do, but the plugin has not been updated for quite some time and it doesn’t work with the newest WP versions.

Any suggestion will be much appreciated.
