SetTitleMatchMode

SetTitleMatchMode is a command used in AutoHotkey, a free, open-source scripting language for Windows. This command controls how the text in the "title" (or caption) of a window is matched against patterns provided in other AutoHotkey commands. When a script needs to identify or interact with a specific window, it often uses its title. SetTitleMatchMode allows the scripter to define the precision and type of matching performed.

There are several modes available. The default mode, SetTitleMatchMode, RegEx, treats the window title as a regular expression. Another common mode is SetTitleMatchMode, 2, which performs a substring match. This means that if the pattern you provide is found anywhere within the window's title, the match is considered successful. Conversely, SetTitleMatchMode, 1, requires an exact match of the entire window title. Selecting the appropriate mode is crucial for accurately targeting the desired windows in an AutoHotkey script, preventing unintended actions on other windows that might have similar but not identical titles. The choice of mode depends on the specificity required for the window identification.
