e93 is a portable window based text editor oriented to the needs of programmers. It was begun in 1993 (thus the name). It uses the mouse, selections, cut/copy/paste, and closely follows the model of editors on the Macintosh and NeXT platforms. * e93 supports columnar selection. It achieves this by allowing multiple pieces of the text to be selected simultaneously (this is perhaps its most unique feature). * e93 imposes no limits on the line length, file length, or number of simultaneous files which it can edit. * e93 is able to handle all 8-bit binary codes without complaint, or confusion. * e93 is highly configurable without recompiling because scripts which control the editor can be written in Tcl. * e93 supports user-configurable syntax highlighting.
