I am very lazy and I would like to always push my commit immediately.
Is there a way to make commit+push the default? I would like to use as little keystrokes as possible.
I think this is the answer to your question (based on PhpStorm):
Unfortunately, there is no option to change the default behavior for the button.
However, you may want to disable buttons grouping via "Settings - Appearance & Behavior - Appearance | Window options -> Allow merging buttons on dialogs."
In this case, you will have a separate button for "Commit and Push".
As an option, you could use a keyboard shortcut (Ctrl+Alt+K on Windows).
on MacOS the keyboard shortcut is Shift+Command+K (symbols: ⇧ + ⌘ + K, see this page for an explanation about MacOS shortcut commands).
I hope this can help (PyCharm Professional 2019.3).
Some news...
Starting 2020.3 Commit and Commit & Push buttons are both visible now
