SciTE – Lightweight GTK-based Programming Editor
SciTE is currently available for Intel Windows (XP or later) and Linux compatible operating systems with GTK+. It has been run on Windows 7 and on Fedora 12 and Ubuntu 10.10 with GTK+ 2.20.
Text editing in SciTE works similarly to most Macintosh or Windows editors with the added feature of automatic syntax styling. SciTE can hold multiple files in memory at one time but only one file will be visible. Rectangular blocks of text can be selected in SciTE by holding down the Alt key on Windows or the Ctrl key on GTK+ while dragging the mouse over the text. The modifier key used on GTK+ can be changed with the rectangular.selection.modifier property.
There are two panes in SciTE, the editing pane and the output pane. The output pane is located either to the right of the editing pane or below it. Initially it is of zero size, but it can be made larger by dragging the divider between it and the editing pane. The Options | Vertical Split command can be used to move the output pane beneath the editing pane.
SciTE can perform commands to compile or run source files with the output from these commands directed into the output pane.
