Login-box inserts into all your pages a "lightbox style" login form, that can be opened with Ctrl + E, making faster the authentication proc
Login-box 2.0 has a practical and self-explanatory options panel where you can change your settings, it is accessible within the page "Design", into the panel of WordPress.
Alternatively, you can edit the options directly into a PHP file, which eliminates the database queries and significantly improves the performance if your blog has a lot of access. Open the login-box-config-sample.php, edit the following lines and at the end, save it with the name login-box-config.php.
In this line, put the name of the theme that you like to use. You can download new themes on web or make your theme based in the defaults "wp25" and "wpclassic".
Choose the key (case insensitive) that will be open/close Login-box with Ctrl or Alt. Note that some keys executes especial functions in your browser (and in browser of your readers!). and them will be cancelled by Login-box. (e.g. Ctrl + A selects all). I recommend that you leave the default value "e".
Also, you can define false here and deactivate the Ctrl use of Login-box. So, you can put "a" in LB_KEY, and open Login-box with Alt + A. Ctrl + A will be selects all normally.
Here, choose on you will be redirected when success login. If true, you will be back to the actual page; if false, you will be redirected to the WordPress Dashboard.
Here, set true if you want that Login-box opens with a fade-in effect; Set false if not want.
Here, leave true and the Login-box will be automatically inserted into your blog (see steps 3 and 4 of the "install" section); If you prefer to choose where the Login-box will appear in your blog, set here as false and put in its theme, the code
<?php loginbox(); ?> where you want it to appear.
