The Canonical Partner repository offers some proprietary applications that don't cost any money to use but are closed source.

<app>Synaptic Package Manager</app> is more powerful and can do some software management tasks which <app>Ubuntu Software Center</app> can't. Synaptic's interface is more complicated and doesn't support newer Software Center features like ratings and reviews and therefore isn't recommended for use by those new to Ubuntu.

Synaptic is a powerful but complicated software management alternative to Ubuntu Software Center.

Install additional software

The Ubuntu development team has chosen a default set of applications that we think makes Ubuntu very useful for most day-to-day tasks. However, you will certainly want to install more software to make Ubuntu more useful to you.

To install additional software, complete the following steps:

Use the Ubuntu Software Center to add programs and make Ubuntu more useful.

Flash the screen for alert sounds

Your computer will play a simple alert sound for certain types of messages and events. If you have a hard time hearing these sounds, you can have either the entire screen or your current window visually flash whenever the alert sound is played.

Open <gui>Universal Access</gui> and select the <gui>Hearing</gui> tab.

Turn on sticky keys

Type keyboard shortcuts one key at a time rather than having to hold down all of the keys at once.

<em>Sticky keys</em> allows you to type keyboard shortcuts one key at a time rather than having to hold down all of the keys at once. For example, the <keyseq><key>Alt</key><key>Tab</key></keyseq> shortcut switches between windows. Without sticky keys turned on, you would have to hold down both keys at the same time; with sticky keys turned on, you would press <key>Alt</key> and then <key>Tab</key> to do the same.

For example, if you have sticky keys turned on but press <key>Alt</key> and <key>Tab</key> simultaneously, sticky keys would not wait for you to press another key if you had this option turned on. It <em>would</em> wait if you only pressed one key, however. This is useful if you are able to press some keyboard shortcuts simultaneously (for example, keys that are close together), but not others.

Switch <gui>Sticky Keys</gui> on.

Select <gui>Disable if two keys are pressed together</gui> to enable this.

You might want to turn on sticky keys if you find it difficult to hold down several keys at once.

You can have the computer make a "beep" sound when you start typing a keyboard shortcut with sticky keys turned on. This is useful if you want to know that sticky keys is expecting a keyboard shortcut to be typed, so the next key press will be interpreted as part of a shortcut. Select <gui>Beep when a modifier key is pressed</gui> to enable this.

Enable visual alerts to flash the screen or window when an alert sound is played.

Use the <gui>Acceptance delay</gui> slider to control how long you have to hold a key down for it to register.

You can have your computer make a sound when you press a key, when a key press is accepted, or when a key press is rejected because you didn't hold the key down long enough.

Switch <gui>Slow Keys</gui> on.

Turn on <em>slow keys</em> if you would like there to be a delay between pressing a key and that letter being displayed on the screen. This means that you have to hold down each key you want to type for a little while before it appears. Use slow keys if you accidentally press several keys at a time when you type, or if you find it difficult to press the right key on the keyboard first time.
