Description Stephen Colebourne CLA 2021-11-18 04:44:10 EST 
I'm using version: 2021-12 (4.22), Build id: I20211023-1800

If the caret is at the start of a line (in a Java file or an XML file), pressing the Home key causes the caret to move to the start of the document. This is a change in behaviour from previous releases, and I believe it to be a bug.

Note that I have smart caret positioning at line start/end switched off. The correct behaviour is that the caret should not move if it is already at the start of a line.

Can you please try with I20211117-1830 (4.22 RC1 candidate)?

I can't reproduce your issue with that one (on Linux).
Comment 3 Stephen Colebourne CLA 2021-11-18 12:07:51 EST 
Full reproducible by me on Windows 10.

* Downloaded I20211117-1830. 
* Unzipped and opened with a brand new workspace. 
* Set preference to have smart caret positioning at line start/end switched off.
* Create general project
* Create file a.txt
* Enter some text on a few lines
* Press the Home key twice
* First press goes to the start of the line (correct)
* Second press goes to the start of the document (bug)

Note that the bug is linked to setting the smart caret positioning preference OFF. If I have that set on ON then the bug does not happen.

I've missed that, I can reproduce. 
Is this a regression in 4.21?
Reminds me on bug 575942.
@Mickael: could you please check?
Comment 5 Mickael Istria CLA 2021-11-18 12:31:32 EST 
I can reproduce it on Linux with a recent build.
I cannot reproduce it with 4.21.
So this seems to be a regression.
