OK. I'm going to be 38 at my next birthday (March 2008). I've come to the realization that because I've been buried in crap at work, my time and abilities to explore the features in software and on the web have become limited. Back in my teens and 20s, I would take an application and learn nearly every menu function, play with every setting or option and generally tried to get the most out of the software that I could. These days I just use the basics + a few keyboard shortcuts here and there. I also spend about 50% of my time at the CLI. Now, not being one to think I'm "old" necessarily, I want to get back to learning more about applications, but not necessarily reading manuals, multiple web sites and forums and so on. I'm looking for tips. Especially really obscure but useful ones if possible. Not just for me either, but also for others who are reading this and might find quick tips very useful. I would like this to be multiplatform so no fighting about that. Windows, Linux, Mac and dead OSes :) are all invited. My desktop platform is Gnome running on Gentoo Linux, so I'll likely be focusing on Gnome stuff. Also, no disparaging comments about what other people consider helpful (unless they're really fucking stupid. Just kidding). If possible, format your subject like this for "quick reference": Platform:Application:Tip Description. Example: Gnome:Nautilus File Manager:File Association I'll post my tips below as I can think of some.

Sorry! There are no comments related to the filter you selected.

Gnome:Nautilus File Manager:File Association (1)

eno2001 (527078) | more than 6 years ago | (#21740128)

How:

1. Right click on a file of a type you are interested in (MP3, JPG, TXT) and select the Properties menu item from the context menu. Click on the "Opens With" tab
2. Click the "Add" button to get the application selection dialog.
3. You may select any application from the menu tree below (it mirrors the Gnome application menu which is like Window's "Start" menu) to associate with this file type and click the "Add" button
3. You may also enter a custom command (Applications that you've built in /usr/local or even custom scripts) by expanding the "Use custom command" option below and then in the field that appears associate it with the file type. Click the "Add" button to exit the dialog
4. Repeat the above steps for any applications you'd like to associate with this file type
5. You can then select the default application by clicking the radio button next to your preferred application
6. Once you've added as many applications as you'd like associated, click the "Close" button
7. To make use of the alternate applications, right click a file of the type you associated and select the alternate application from the "Open With" menu.

Why it's useful to me?

I use this feature in order to watch movies using one of two custom scripts. The default custom script (calls Xine with a ton of options) just plays the movies normally on my media center. The alternate one (which is really the same script symlinked to a different name and parsing the $0 argument to run a different set of functions) plays the video on the main screen but routes the audio via WiFi to the laptop so that I can use headphones. I can't just plug the headphones into the media center since it's a floor below so I don't have a computer (or amp, or satellite tuner) sitting in the living room like any other normal person. :)

Gnome:Nautilus File Manager:Hidden Folders/Files.. (1)

eno2001 (527078) | more than 6 years ago | (#21740176)

Gnome:Nautilus File Manager:Hidden Folders/Files in File Selector Dialogs

NOTES: This is available in Gnome 2.x but is more or less hidden in earlier versions. Newer versions don't require the keyboard shortcut. When you are presented with a File Selector in Gnome, it does not display the hidden files and folders no matter what your settings in Nautilus are. As a result, if you want to change into a directory within the file selector called .icons (a hidden folder in Gnome) it is not readily apparent how to do so.

1. In the file selector dialog, press Ctrl-L. This will open the Location field. You may then type the name of your hidden directory and the file selector will navigate to that location
2. If you enter a hidden file into this field, then the file selector will open the hidden file within your application
3. In newer versions of Gnome there is now an icon that looks like a notepad with a pencil. The help text says, "type a location". Toggling this on or off will allow give you access to the Location field.

Why it's useful to me?

Because when I'm creating custom icons in Gimp for various apps, I like to save them into ~/.icons/ and I couldn't figure out how to f*cking do it a few years back. Thanks to a tip from one of the Slashdot crew, I've been using Ctrl-l ever since.

Various:Firefox:Organizing Tabs and Bringing... (1)

eno2001 (527078) | more than 6 years ago | (#21740230)

Various:Firefox:Organizing Tabs/Bringing Back An Accidentally Closed Tab

NOTE: While this may seem obvious to some, I swear it didn't work when I first tried it way back when. In version 2.0.0.4 is does!

1. Open three or more tabs (more dramatic effect with more than two) and navigate to three or more different sites
2. Click and drag the right hand tab and place it between the first and second tabs then release

Why it's useful to me?

I just like knowing that my sites appear in a certain order that way I can quickly switch between frequently visited sites and less frequently visited sites with ease.

1. If you accidentally close a tab you didn't mean to close, you can bring it back by pressing Ctrl-Shift-t

Various CLI logins:Telnet, FTP, etc:Undoing Typos (1)

eno2001 (527078) | more than 6 years ago | (#21740326)

Most Platforms with CLI logins:Telnet, SSH, Console, FTP, SMBClient, GNU Screen (unlock), Conserver:Undoing mistyped passwords

NOTE: This doesn't apply totally across the board and is likely connected to readline, but I've had it work on: Cisco telnet logins, OpenVMS logins, ssh and telnet to remote Unix/Linux hosts.

1. Enter your login ID on the remote system in question
2. Typo your password when prompted or lose your place when typing (uh oh)
3. Press Ctrl-u
4. Re-enter the password and press the enter key
5. Marvel at how you lived without this knowledge

Gnome:Nautilus File Manager:Remote Filesystems Via SSH

NOTE: This is different from the "Connect to Server" dialog but seems to work out better in terms of "double clicking" on files and having them open in their associated applications. It also makes use of ~/.ssh/config as well as any authentication keys so you can have passwordless connections.

1. Make sure that Nautilus has the main focus (if you have any Web browsers open, move to a different desktop or minimize your browser)
2. Press Ctrl-l which will prompt you to open a specified location
3. Enter the URL of your ssh server in the following format: 'ssh://user@server:/path/to/remote/folder'. If you have configured connections in ~/.ssh/config, then you can simply type: 'ssh://customsshconfigname:/path/to/remote/folder'.

Example (I have a server named 'roy' in my ~/.ssh/config and my remote folder path is /mnt/data/mp3):

ssh://roy:/mnt/data/mp3

If I didn't have 'roy' in ~/.ssh/config, I'd have to enter:

ssh://eno2001@roy:/mnt/data/mp3

4. In the Nautilus window that appears, you can then use it as you would a local window. Double click on files to open them or right click and select a specific application. You can drag and drop, etc... All with the goodness of OpenSSH encryption.
