Text Formatting ⇒ 'Undefined control sequence Strong text \strong' issue

[astenix]

Hi all,
can anyone get me an idea about what is happened with my LaTeX document?

My enviromnent:

• Debian: jessie
• Kile: 2.1.3
• Qt: 4.8.6
• KDE: 4.14.0
• TeX Live 2014/Debian
• pdfTeX: 3.14159265-2.6-1.40.15

My very simple document:

Code: Select all

Compilation result with following:
[PDFLaTeX] finished with exit code 1
./test.tex:6:Undefined control sequence Strong text \strong

I'm sorry, but WAT?
How it can be possible?
Am I wrong about it, or '\strong' doesn't exist?

The KOMA-script author provides a search that gives you the name of the package(s) providing a command. -> LaTeX commands (sorry, the site is a bit multilingual)

I was using this, because i don't know a command strong.

Searching a bit further leads me to Does LaTeX define a semantic equivalent of \textbf?. Again, no direct hit, but Martin Scharrer provides a new macro similar to \emph but using \textbf. You can use it in your documents.

Here is his code which you can run directly by clicking on »Open in writelatex«

Run LaTeX here

Let's ask ourself, why doesn't LaTeX provide this command in the first place? \emph is the short form of emphasize. Another possibility to highlight something is to use small caps (uppercase letters at lowercase letters size). Please look at the attached pdf, what catches your eye when looking at the pages in full? Bold face words are always a bit like screaming »Look at me, look at me now!«
Or in other words, a reader turning the page will see some Klecks on the page and immediately look down at it, as there is something disturbing the greyness of the page.

Thank you, Johannes!

I added some remarks in between, not sure if you catched those. If you want to, take a look.
And by the way, welcome to our little community. ;-)
