Modal windows tend to create an abrupt diversion of text input, especially typed input intended for other programs, into themselves. Further, modals usually interpret actuation of the enter key (or in rare cases the presence of a newline in pasted input) as a cue to accept the input and process it—or, in rare cases, may intercept a mouse ...
Selenium Remote Control was a refactoring of Driven Selenium or Selenium B designed by Paul Hammant, credited with Jason as co-creator of Selenium. The original version directly launched a process for the browser in question, from the test language of Java, .NET, Python or Ruby.
Setting or clearing ("unclicking") a checkbox changes the checkbox's state with no other side-effects.Violating this guideline by associating additional actions with the change of state frequently confuses users, because they are used to configuring data in entry controls such as text boxes, radio buttons, and checkboxes and then invoking an action control such as a push button to initiate the ...
Automation Element objects expose common properties of the UI elements they represent. One of these properties is the control type, which defines its basic appearance and functionality as a single recognizable entity (e.g., a button or check box). In addition, elements expose control patterns that provide properties specific to their control types.

A CAPTCHA usually has a text box directly underneath where the user should fill out the text that they see. In this case, "sclt ..was ...
Selenium is found in metal sulfide ores, where it substitutes for sulfur. Commercially, selenium is produced as a byproduct in the refining of these ores. Minerals that are pure selenide or selenate compounds are rare. The chief commercial uses for selenium today are glassmaking and pigments. Selenium is a semiconductor and is used in photocells.
A selenium meter is a light-measuring instrument based on the photoelectric properties of selenium. The most common use of such light meters is measuring the exposure value for photography. The electric part of such a meter is an electromagnetic measuring instrument which is connected to the anode and cathode of a selenium photo cell that ...
An example of graceful degradation by design in an image with transparency. Each of the top two images is the result of viewing the composite image in a viewer that recognises transparency. The bottom two images are the result in a viewer with no support for transparency.
