You can type MicroEMACS instructions in upper or lower case. There are two types of instruction, CONTROL and META.
These are typed while holding down the CTRL key which is signified by the ^ character. For example ^F is generated by pressing the F key while holding down the CTRL key.
These are typed after pressing the ESC key which is signified by M-. For example, M-F is generated by pressing the ESC key and then typing the letter F. Throughout this document, the ESC key is referred to as the META key.
Remember, the CONTROL instructions are typed with the CTRL key and the META instructions are typed after the ESC key.
Sometimes a META or CONTROL instruction will prompt you for more information. This information may be another META or CONTROL instruction or some text.
