问题
In IDEA, we can comment/uncomment lines in java as well as html,jsp, xml files with the same keyboard shortcut combination. I tried doing that in eclipse but was not able to comment out lines in html,jsp and xml files. Is there a way to do it in Eclipse? Also I would like to know whether bulk comment is also available for non-java files.
回答1:
I use Shift+Ctrl+/ to Add Block Comment in both XML and JSP files (works at the line level or for a selected block).
Just in case, if you are looking for a particular shortcut, you can use Shift+Ctrl+L to Show Key Assist (i.e. the Commands and their Bindings).

I believe CTRL+SHIFT+C works in XML, not sure about JSP. I think it lacks consistency in the various editors, and some don't have this shortcut.

I found Ctrl + Shift + C works in JSP too, it works like:
<tiles:insertDefinition name="" >
</tiles:insertDefinition>
<!--<tiles:insertDefinition name="" >-->
<!--</tiles:insertDefinition>-->
add comment tag line by line, and select the sentences, use Ctrl + Shift + C again can toggle remove the comments.
Ctrl + Shift + / add block comment in JSP, works like:
<tiles:insertDefinition name="" >
</tiles:insertDefinition>
<!--<tiles:insertDefinition name="" >
</tiles:insertDefinition>
-->
can use Ctrl + Shift + \ to remove the block comment.
PS: I want to find out, which eclipse shortcut can add/remove <%-- --%> comment in JSP?
回答4:
In eclipse they use same kind of shortcut to do this which is for:
I found Ctrl + Shift + C works in XML and JSP.
Single line
comment Ctrl + /
uncomment Ctrl + /
Multiline
comment Ctrl + Shift + /
uncomment Ctrl + Shift + \ (note the backslash)
Hope this helps!

In Mac, for xml:
Command+/ - To comment a line or selected block of lines
Command+\ - To uncomment a line or selected block of lines
This works in Eclipse Photon (4.8.0)
