## New commands

\newcommand{name}[num]{definition}
\newcommand{\wbal}{The Wikibook about \LaTeX}
This is ‘‘\wbal'' \ldots{} ‘‘\wbal''
=> This is “The Wikibook about LaTeX” … “The Wikibook about LaTeX”
The next example illustrates how to define a new command that takes one argument. The #1 tag gets replaced by the argument you specify. If you wanted to use more than one argument, use #2 and so on, these arguments are added in an extra set of brackets.


### Fastest way to send multiple drafts from gmail

People claim that the fastest way to send multiple email drafts is to use Gmail IMAP with email client like Outlook or Evolution or Thunderbird. But I have found this is not true. Because Thunderbird and Evolution etc. email clients treats the drafts as emails still to be edited. So it is not just simple select all and hit send. Each email draft has to be opened and sent separately. That is a lot of clicks and mouse movements, wasting precious time and energy. I have a better solution which involves minimum keystrokes and mouse usage. Efficiency booster technique for sending emails.
If someone is feeling adventurous and want to try it from the Gmail interface itself, here's how to do it in the fastest possible manner. It involves using the mouse once. Select the first draft. Gmail would open a new email box and put the cursor inside the box to write.Press TAB once to go the Send button.Press ENTER to send. Now Gmail sends it and the box is gone but the highlight goes to the last li…

### How to join audio tracks smoothly in Audacity

Audio tracks can be mixed easily in full fledged video editors like kdenlive or Adobe Premiere but for mixing or joining audio they would not provide the amount of control that audio editors like Audacity provide. The example I am going to show today would demonstrate the range of tools in Audacity that allows us to control the waveform and to mold it to our desire.

Today I am going to take a small track like a small 1 min. clip of storm sound and make a long continuous sounding storm audio clip from it.

STEP 1 : Open file
Open the clip in Audacity.

STEP 2 : Removing unwanted audio portion
There is always unwanted sections of the audio that we have to discard. Select the portion of background noise or unwanted audio.

Press DELETE key.

STEP 3 : Duplicating the track
Now we make a copy of the entire waveform and paste it at the end of the track.

Select the SELECT tool (the one which looks like I). Then select the whole waveform and prss Ctrl+c. Now click approximately at the end of the…
