Assuming it is working correctly, this ensures that other applications cannot "listen in" on your interaction with XTerm via the keyboard or execute a "man in the middle" keystroke logging attack.Īs an indication that the secure keyboard mode has been turned on, XTerm's color scheme should be "reversed", with the normal background color becoming the foreground (text) color, and vice versa. This means, of course, that while you have the secure keyboard mode turned on, you should not be able to use the keyboard to interact with any other applications it is usually only suitable to a very brief interaction, such as entering a password. When the secure keyboard mode is activated, XTerm uses the GrabKeyboard protocol request to try to ensure that all keyboard input goes directly and solely to XTerm. Selecting that will activate a secure keyboard mode, which can provide some protection against keystroke logging when entering passwords and typing other things for which you might want a little extra assurance of privacy. In XTerm's left-click menu (accessed by pointing your mouse at the XTerm window and holding down both the Ctrl key and the left mouse button) is a "Secure Keyboard" option. Secure KeyboardĪs mentioned in the article," Use pwsafe as a keyboard shortcut driven X tool," XTerm offers a handy security feature that is not present in many other terminal emulator applications. For XTerm's onNClicks resources, the line setting means it should select the entire line, including the newline. * as indicating any number of almost any type of character at all. Those of you familiar with regular expression syntax will recognize + as indicating one or more characters that are not either a space or a newline, and. The onNClicks resource settings in my app-defaults/XTerm file look like this: xterm*on3Clicks: regex + The line expression tells it to just highlight the entire line, while regex expressions allow you to use a limited regular expression syntax to tell it what characters to match when determining what characters are eligible to highlight when adjacent to other eligible characters. Special character matching expressions can be used to tell what kinds of adjacent characters to highlight on a given number of clicks with onNClicks resource settings, where the N is actually a number up to five.

On FreeBSD, it is located at /usr/local/lib/X11/app-defaults/XTerm on Debian GNU/Linux, it is located at /etc/X11/app-defaults/XTerm instead.

To configure XTerm's click-to-highlight behavior, find your app-defaults/XTerm file. Luckily, XTerm's click-to-highlight behavior is pretty trivially configurable. This makes highlighting things like URLs, hyphenated words, and cryptographic hashes into a click-and-drag operation, which highly efficient command line users often find frustratingly tedious. Click three or more times, and you get the whole line, newline character and all. Click twice, and it highlights "word" text, but stops on almost anything that is not alphanumeric. The default click-to-highlight behavior of XTerm is miserable.

The truth of the matter, though, is that XTerm is full of functionality that most people never even notice. It is easy to dismiss XTerm as primitive and feature-poor when you are used to gnome-terminal, KTerm, and other graphical tabbed terminal emulators.
