A keymap editor for the X window system xkeycaps is a graphical front-end to xmodmap. It opens a window that looks like a keyboard; moving the mouse over a key shows what KeySyms and Modifier bits that key generates. Clicking on a key simulates KeyPress/KeyRelease events on the window of your choice. It is possible to change the KeySyms and Modifiers generated by a key through a mouse-based interface. This program can also write an input file for xmodmap to recreate your changes in future sessions.
This program gives you all the features you need to create basic- to intermediate-level vector graphics, including bezier curves, lines, rulers, and m (Not Specified)
