.SH DESCRIPTION
|
|
.B kte
|
|
is a small, fast, and understandable text editor with a terminal-first
|
|
experience. It preserves ke's WordStar/VDE-style command model with
|
|
Emacs-influenced ergonomics. The core uses ncurses in the terminal.
|
|
|
|
By default, .B kte
|
|
runs in the terminal (ncurses) frontend. If the binary was built with GUI
|
|
support, the same editor core can be shown with an ImGui-based GUI by passing
|
|
.B --gui
|
|
or by invoking the GUI-first target
|
|
.BR kge (1)
|
|
when available.
|
|
|
|
If one or more
|
|
.I files
|
|
are provided, they are opened on startup; otherwise, an empty buffer is
|
|
created.
|
|
.SH OPTIONS
