Permitted only in a case of need (e.g., someone is about to do an aveira and you want to write them a note saying not to do it). Otherwise not allowed.
I personally witnessed Rav Avigdor Nebenzahl shlit"a during shacharis would take his three steps before he finished גאל ישראל as a הידור of סמוך גאולה לתפילה - that the blessing of redemption should be close to the prayer. He did this as well for Maariv. He takes his three steps as the tzibbur is saying the final of Amen of קדיש.
