### Memory usage
When you first run 4LIVE, it will load only a small code stub in low memory (in page 3, just below the DOS 3.3 vectors). This stub will load the rest of 4LIVE directly into $D000 in LC RAM bank 1. The stub clobbers the memory range $800-$8FF in main memory.
When you first run 4LIVE, it will load only a small code stub in low memory (in pages 2 and 3, just below the DOS 3.3 vectors). The stub clobbers $800-$8FF in main memory in order to load the rest of the 4LIVE code and your data file directly into $D000 in LC RAM bank 1.
Thereafter, 4LIVE stays resident in page 3 ($300-$3CF) and in LC RAM bank 1 ($D000-$DFFF), but it does not clobber any other region in main memory.

* `<Ctrl+@>` or `<Esc>` exits the 4LIVE editor.
* Arrows move freely up, down, left, and right. On an Apple II+, you can use `<Ctrl+K>` and `<Ctrl+J>` in place of up and down arrows.
* `<Return>` moves the cursor to the beginning of the next line. It does not erase any text on the current line. It will wrap around from the bottom of the screen to the top.
* `<Ctrl+N>` clears the editor screen and erases all your data.
* `<Ctrl+I>` imports the "real" text screen you were looking at before you entered the editor (like taking a text screenshot). This overwrites the entire scratchpad and erases all your data.
