For Windows, IrfanView offers a powerful screenshot tool with these features:
- Custom filenames (number and timestamp) such as 000001_20170324110124.Screenshot.png (not an actual filename of a file I have, just an example. I did not use the timestamp of right now (20181107…) to avoid confusions with GMT). The number is useful for navigating to a screenshot quickly by a file manager's/terminal's automatic filename completion and to add oversight. The word “Screenshot” makes it easier to find screenshots using file search.
- Does not reserve clipboard. (if I wish to take a screenshot to the clipboard, I can just manually use the gnome-screenshot command)
- Ability to save screenshot immediately. No need to confirm or interact with a dialogue that may accidentially be closed by pressing the Escape key, eliminating the screenshot.
IrfanView just makes a Windows notification sound each time a screenshot capture is triggered. But nothing beyond that.
Mate screenshot offers no possibility to save the screenshot without encountering the confirmation dialogue. At least no delay, memorizes path,works without sound or screen effect and does only reserve the clipboard if manually wanted by the user. Edit: On Xfce, mate-screenshots from mate-utils does make a camera noise. Not that I think the noise is ugly but it might block a word from background audio I am listening to.
Gnome screenshot uses a screen blackout effect which I would not prefer. Not that it looks ugly, it just blocks the entire screen for a short moment. Additionally, it does not memorize the previous screenshot folder and always sets it to ~/Pictures. At least, gnome-screenshot and mate-Screenshot both support bookmarks.
How can I capture a screenshot and save it immediately with the press of one button?
If I can set a bonus key such as G2 (not available on all keyboards), that would be great. Also custom filenames would be nice to have, but mainly, I just wish to capture screenshots with the press of one button.
