This is a list of syscalls that are related to text and expression editing, and are involved in one or more of the following tasks:

• Drawing a string or math expression on VRAM, possibly with a cursor, for editing purposes (PrintXY, for example, doesn’t belong here);
• Editing a string or math expression, adding or removing characters, changing the cursor position and other display parameters, in response to a key input (which is not necessarily captured by the syscall itself);
• Letting the user select from a list of special characters;
• Letting the user manipulate the clipboard contents.

GetKey plays an important role in the usage of many of these syscalls, as the source for keyboard input, but is not eligible for this category as its main focus is not text or expression editing.
