Tkedit, therefore, has "tcl" as its macro creation language - this provides a means of extending the editor (as you can with emacs). Tkedit provides a wide range functions, all based on simple, single key presses. The editor works intuitively and gives a maximum of information with a minimum of effort. Other features include multiple buffers with split views, key macro recording, C and TCL macros, and ctags, make and ispell support.
