Space bar and other keys deleting characters

Problem: typing some text and if you have to fix some typo your space bar starts deleting characters. Could be a big issue in the command-line. Well for most text applications you can switch between overwrite and insert mode but they all do a poor job at letting you know what mode you’re in.

Solution: “Insert” key, you can press the insert key to switch modes. Really simple but a major pain if your mode changes.
