In case of doubt choose the first or the second command as shortcut in your favorite desktop environment.
A systray icon will be in your system's panel while Flameshot is running. Do a right click on the tray icon and you'll see some menu items to open the configuration window and the information window. Check out the information window to see all the available shortcuts in the graphical capture mode.
Shortcuts
These shortcuts are available in GUI mode:
| Keys | Description |
|---|---|
| ←↓↑→ | Move selection 1px |
| SHIFT + ←↓↑→ | Resize selection 1px |
| ESC | Quit capture |
| CTRL + C | Copy to clipboard |
| CTRL + S | Save selection as a file |
| CTRL + Z | Undo the last modification |
| Right Click | Show color picker |
Shift + drag a handler of the selection area: mirror redimension in the opposite handler.
Considerations
-
Not working on Wayland
-
If you are using Gnome you need to install the TopIcons extension in order to see the systemtray icon.
-
In order to speed up the first launch of Flameshot (DBus init of the app can be slow), consider starting the application automatically on boot.
-
Press
EnterorCtrl + Cwhen you are in a capture mode and you don't have an active selection and the whole desktop will be copied to your clipboard! PressingCtrl + Swill save your capture in a file! Check the Shortcuts for more information. -
Execute the command
