a checkbox) is not checked, displayed when an object (e.g. If NVDA is installed and running on your system, you can open the add-on directly from the browser to begin the installation process as described below. Pressing three times will copy it to the clipboard, reads all the controls in the currently active window (useful for dialogs), Reports the Status Bar if NVDA finds one. The third lets you control if this Welcome dialog should appear each time NVDA starts. This can make it difficult to skim a long list of items, for example, as you will need to continually move your finger to find the start of the item. This category contains the following options: This field sets the maximum length of a line in browse mode (in characters). I haven't watched that video yet, though.Enable this option while proof reading documents in applications such as WordPad, where formatting is important. This inherently means that depending on the functions used, some ncurses-based programs are going to be at least somewhat inaccessible. Screen-based programs are inherently visual, and unless programs offer some kind of line-based alternative (for example, ex is the line-based alternative to vi), it could be difficult for blind people to use these programs. These programs will be much harder for a screen reader to process because even if the screen reader knows enough to switch to a specific screen-based mode of parsing the output, it has no way of knowing which parts of the terminal are important and which are just chrome.
This includes things like nano, vi, tmux, mc, lynx, mutt, etc. Screen-based programs take over the screen of the terminal in order to present their own interface. Programs in this category will be accessible for the most part.
This includes things like grep, awk, everything in the coreutils package (ls, dd, uname, etc), and most commands which make up the core Linux CLI experience. Line-based programs are those that simply print their output to stdout/stderr and don't attempt to do any fancy stuff to take over the terminal screen. (I haven't watched the video yet.)Ĭonsider that there are two major methods that programs can use when outputting to the terminal - line-based and screen-based. I'm not blind myself and don't have much experience with screen readers in Linux, but I'd be surprised if the more popular programs in the terminal (like tmux) were accessible.
