title: Netbeans Lowercase Shortcut Not Working
body: <p>Netbeans has a <a href="https://netbeans.org/project_downloads/usersguide/shortcuts-80.pdf" rel="noreferrer">nice set of keyboard shortcuts</a>, but unfortunately, I can't seem to get all of them to work. Specifically, there's a keyboard shortcut for converting selected text to lowercase: <kbd>Ctrl</kbd>+<kbd>U</kbd> <kbd>L</kbd>. However, no matter how many times I try this (or variations on it), <s>nothing happens</s> I just get a 'ding' sound (it used to be that nothing happened). I check the Keymap option on Netbeans, and it shows that this is still the shortcut mapped to <kbd>Ctrl</kbd>+<kbd>U</kbd> <kbd>L</kbd>:</p>

  <p>What am I doing wrong? How can I use this keyboard shortcut?</p>
  
  <p>Note that <kbd>Ctrl</kbd>+<kbd>;</kbd> or <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>;</kbd> works just fine, among many other shortcuts.</p>
