A useful shortcut replaces an action you already understand. Start with a small set, practice it in context, and keep the pointer available when a key is not memorable.
Read shortcut notation
Ctrl + C means hold Ctrl, press C, then release both. The plus sign describes a combination; you do not type +.
Five editing shortcuts
Practice these in a disposable text document:
Ctrl+A: select all text in the current area.Ctrl+C: copy the selection to the clipboard.Ctrl+X: cut the selection, preparing it to move.Ctrl+V: paste the clipboard contents.Ctrl+Z: undo the most recent supported action.
After copying, the original remains. After cutting and pasting, the selected text moves. Undo availability depends on the application and action, so it is not a substitute for saving or backups.
Search inside the current application
Ctrl + F commonly opens Find inside the application or document you are using.
In a browser, it searches the current page. In Files, it searches from the current folder. In a text editor, it searches the open document.
This is context: the focused application decides what the shortcut means.
Navigate Files more quickly
In Files:
Ctrl+Lfocuses or exposes the location field so you can read or enter a path.Ctrl+Hshows or hides dotfiles.Ctrl+Nopens a new Files window.Deletesends the selected item to Trash under ordinary conditions.
Before pressing Delete, look at the selected item. Keyboard speed should not remove the verification step.
Reach applications and windows
- Press
Superto open or leave the Activities overview. - Press
Super+Ato show applications on the documented current setup. - Press
Super+Tabto switch applications. - Press
Super+Page UporSuper+Page Downto switch workspaces. - Press
Alt+F4to close the focused window.
Many people expect Alt + Tab from another desktop. Ubuntu shortcuts can be customized, and environments differ. Open Settings → Keyboard → View and Customize Shortcuts when the expected binding does not match the documented one.
Lock and capture the screen
Super+Llocks the screen.Printopens the screenshot interface.Alt+Printcaptures the focused window on the current documented setup.Shift+Printcaptures the full screen on the current documented setup.
The next lesson explains where captures go and how to select a region.
A shortcut may belong to the application
Ctrl + L in Files exposes a location. In a web browser, the same keys usually focus the address bar.
Ctrl + C copies in ordinary graphical applications. A terminal uses a different copy shortcut because Ctrl + C has another command-line meaning. Path 3 will teach that before expecting you to use it.
When a shortcut surprises you, ask two questions:
- Which window has keyboard focus?
- Is the shortcut controlled by Ubuntu or by that application?
Accessibility alternatives
Shortcuts are optional. Menus, buttons, and search remain valid ways to work.
If holding several keys is difficult, Ubuntu accessibility settings include Sticky Keys, which allows supported combinations to be pressed one key at a time. Keyboard navigation also uses Tab, arrow keys, Enter, Space, and Esc to move through controls.
Common mistakes
Typing the plus sign. Hold the named modifier and press the other key.
Copying when nothing is selected. Select the text or file first and confirm its highlight.
Pasting into the wrong window. Check focus before Ctrl + V.
Using Ctrl + A without checking context. It can select an entire document or all files in a view.
Assuming every application supports Undo. Verify the result and save important work.
Memorizing a hundred bindings. Learn a shortcut when it replaces a task you perform repeatedly.

Knowledge check
Which shortcut solves this task?
Choose shortcuts for opening the application overview, finding a word in the current document, showing hidden files in Files, undoing an edit, and locking the screen. Explain which one depends most clearly on application context.
