If you read the version history and even the new beta's changes, you'll see that the right ALT was done on purpose and is now being updated to work as expected on US keyboard layouts. Right Ctrl works fine. I just verified that by copying text and the control codes were copied along with the text. And Ctrl-V with the right CTRL also works.
Better options for formatting text in windows have been suggested before and I'm sure those are probably already on Khaled's list. You do have some options in the meantime. Dialogs and picture windows both allow you a lot more control in text output and formatting.
