Basics

Pressing ALT + X on your keyboard will open a small box in the right corner of the status bar. Use it to enter the NumExt commands.

Since version 0.6 a NumExt clickable label has been inserted under the Tools menu of the main menu. In case Alt + X is used by another addon or menu, you can set up a shortcut key by typing (execkey z) for "Alt + z". The clickable "NumExt (exec)" enables the command box as in the shortcut key.

Windows only

In addition to the standard CTRL + [number] key combinations, you can use the following ones:

ALT + 1 will jump to tab number 9;
ALT + 2 will jump to tab number 10;
ALT + 9 will jump to tab number 17.

The ALT + [number] shortcuts were created in order to overcome Firefox's limits of AccessKeys Control to tabs 1 to 8.

help

Displays this help in case you need to look up something.

update

Notifies you wether or not you are using the lastest version of NumExt.

[number]

You can simply type in the number of the tab you want to jump to.

open <URL>

Opens URL in a new tab. For example: open http://google.com

hide [number]

Hides the tab number specified. If no number is specified, it will hide all tabs but the current.

Tabs will be hidden, not closed.

show [number]

Unhides previously hidden tabs (see the hide command). It unhides the specified tab. If no number is specified it unhides all hidden tabs.

title [number] [title]

Changes the title of the specified tab to title. If no number is specified it changes the title of the current tab. For example: title 3 My Page

col [alias] [number] [title] <colour>

Changes tab colour. This command is a bit more complex to use, here are the possible options:

  • col [number] title <colour>
    Changes the title colour of the selected tab, for example: col 3 title blue
  • col [number] <colour>
    Changes the background colour of the selected tab, for example: col 3 red
  • col <colour>
    Changes the background colour of the current tab, for example: col aqua
  • col title <colour>
    Changes the title colour of the current tab, for example: col title azure
  • col alias {a - e} <colour>
    NumExt ships with 5 alias slot for you to save your favorite colour for easy access by using single letter shortcuts (from a to e). For instance, instead of typing col AntiqueWhite, you can save AntiqueWhite in the alias slot a and just type col a. For example, to register AntiqueWhite in slot a, type: col alias a AntiqueWhite You can then assign the colour AntiqueWhite, say, to tab 3: col 3 a

Keep in mind, that colour can be a normal colour name or simply an hexadecimal colour value such as #FF0045. For a list of all colours you can use, refer to the HTML colour names. Be creative!

nocol [number]

Resets the colours of the previously coloured tabs (see the col command) to your default theme. It resets the specified tab number colour. If no number is specified, it resets the colour of the current tab.

reload [number]

Reloads the specified tab number, or the current tab if no number is specified. For example, if you currently are on tab number 8 and want to reload tab number 10, you can simply type: reload 10

nonum

Disables tab numbering altogether.

num

Restores previously disabled (see num command) tab numbering.

execkey <key>

Changes the shortcut key for accessing the command line (which is normally ALT + X). For example, if you want to change your shortcut to ALT + Z, you type: execkey z If you are having troubles with the default shortcut key (i.e. if it is bound to something else), you can still access the command line from the Tools menu (Tools > NumExt (exec)).

sep <separator>

Changes the separator symbol between the tab number and the tab title. By default, you only get a blank space, but you can change it to whatever fits you better. For example, if you want to use the symbol #, just type: sep #

assist [on | off]

By default NumExt comes with a command assistant, that helps you remember command syntax while you type. With this command you can turn this feature off and back on. To turn it off type: assist off To turn it back on, type: assist on

close [number | numbers | range]

Closes the current tab if no number is given. Else it closes the specified tabs, or a range of tabs. To close tab number 4, 6 and 9 type: close 5 6 9 To close tabs from 3 to 7 type: close 3:7
