Command Prefix

The default standard prefix to a command is a / character, however you can specify another character if the / key is hard to access on your keyboard. Regardless of the character you choose here, mIRC still recognizes the / character and uses it internally.

Window buffer

This limits the scrollback buffer to the specified number of lines. Note that if a scrollback buffer already contains more than the specified number of lines it will be shortened. You can always use the /clear command in a window to clear the scrollback buffer completely. If you are scrolling back through the buffer, lines will not be removed until you return to the bottom of the buffer.

Line separator

You can specify a line separator to be used in the status window. You can use a space to have a blank line. If you leave the box empty, lines in the status window will not be separated.

Keys

ESCape key minimizes window

To make a window minimize whenever you press the ESCape key, enable this option.

Control+K pops up color index

If this is turned on, mIRC will pop up a color index dialog whenever you press Control+K in an editbox to insert a color code.

Hotlinks only when shift key pressed

By default, when you move the mouse over an address/nickname/channel/etc. the mouse turns into a Hotlink pointer. By turning this option on, the hotlink will only appear if you have the shift key pressed.

Right-click in listbox selects line

If turned on, this feature makes mIRC select the line under the mouse when you right-click in a listbox.

Titlebar right-click needs shift key

If turned on, you have to hold down the shift key when you click your right mouse button on a window titlebar to open/close the window.

Control+Tab uses switchbar order

This changes the normal Control+Tab behaviour when switching windows so that it follows the current window order on the switchbar.

Tab key changes editbox focus

This makes it easier to switch to the second editbox in a channel window. The tab key still works as nick/channel/etc. completion if the cursor is next to a word. If enabled, you need to use Shift-Tab instead of Tab to cycle between the list of nicks that messaged you.
