If you only have a two button mouse you -can emulate the middle button by holding down shift key -whilst pressing the right button. - -Button 1, 2, and 3 are used to refer to the left, -middle, and right buttons respectively. - -THE POP-UP MENU - -Pressing and holding down button 3 on the desktop or -shell window will give you a menu with the following -options: - - * New - create a new window - * Resize - reshape a window - * Move - move a window without reshaping it - * Delete - close a window - * Hide - hides a window from display (it will appear - in this menu) - * <label> - the label of a hidden window, - selecting it unhides it - -You select an item by releasing the button over the -menu item. rio uses the same button that started an -action throughout that operation. If you press another -button during the action the operation is aborted and -any intermediate changes are reversed. - -The menu acts as a action verb selector which then -requires an object (i.e. window) to be picked to -indicate which window the verb is to act on. A further -mouse action may then be required. - -EXAMPLES - -After selecting New, the cursor will change into a -cross. Using button 3 again, you should then drag out -a rectangle to indicate the size and location of the -new window. When you release the button a new window -will be created. - -New windows will contain the rc shell. Invoking a rio -program from the shell will allow that program to take -over the window. As there is no job control in the -shell (e.g. &, fg, bg), you just create another window -if you want to run another program concurrently. - -To Resize a window, you select Resize, then click -(remember using the same button that started the -action, i.e. button 3) on the window you want to -resize. The cursor will change to a cross-hair theat -will allow you to drag out the desired shape of the -window. - -After selecting Move, click and keep the button -depressed over the window you want to move, then move -the mouse to move the red rectangle that represents the -new location you want. Release the button to finish -the action. - -Delete and Hide both operate by requiring you to click -on the window you wish to respectively Delete or Hide. - -WINDOW CONTROL TIPS - -Clicking on a window brings it to the front. - -You can directly change the shape of a window by -clicking and dragging on the edge or corner of the -window border. Button 1 or 2 will allow you to drag -the edge or corner to a new size, and Button 3 will -allow you to move the window. - -The pop-up menu remembers the last command chosen, so -as a short cut you can just press and release button 3 -without moving the mouse between pressing and releasing -to select the previous command again. - -BASIC TEXT CONTROL - -Unlike in other systems, the text cursor can only be -controlled by the mouse or the side-effects of certain -commands. - -Clicking with button 1 will move the text insertion -point (indicated by an I-beam) to just before the -character closest to the mouse pointer. Dragging -across a section of text will select that portion of -text. It may be useful to know that the insertion -I-beam represents an empty selection (between two -characters). In text editors, the current selection is -known as "dot". - -In the shell window button 2 will invoke a pop-up menu. -Most of it's commands operate on dot. - - * cut - moves the contents of the dot to the clipboard - if dot is non-empty - * paste - replaces dot with the contents of the clipboard - * snarf - copies dot to the clipboard - * plumb - sends dot (or text surrounding dot, if dot is - empty)to the plumber. - * send - completes the current input line with the dot, - if it is non-empty, or the contents of the clipboard. - If the dot is non-empty it does a snarf at the same time. - * scroll - toggles the automatic scrolling of the window - on output. - -Double-clicking will allow you to automatically select -a section of text surrounding that point. The -selection is made by an analysis of appropriate -delimeters. A whole line is selected by -double-clicking at either end of the line. A quoted or -bracketed selection is made by double-clicking just -inside of the quote or bracket. - -SCROLLING - -The arrow keys will let you scroll up or down by half a -page at a time. - -Clicking button 1 on the scrollbar scrolls up by half a -page. Button 3 scrolls down by half a page. Button 2 -jumps to position in the document relative to the -position on the scrollbar clicked. Holding a button on -the scrollbar will have the effect of invoking the -clicking action continuously. - -The white elevator box on the scrollbar is sized -proportionally to the proportion of the document that -is currently visible. - -Scrolling does not affect the text cursor. - -RIO AND THE RC SHELL WINDOW - -Rc is a command interpreter for Plan 9 that provides -similar facilities to UNIX's Bourne shell. See the -additional references at the end of this document for -information specifically about rc. - -Rio provides some additional features that enhance the -interface to programs that use the text console. The -rc shell command interpreter is one such program. - -Rc commands are typed after the prompt on the last line -of the text buffer. The commands are sent to rc only -after each newline so line editing may be performed if -desired. You can move the cursor and edit the previous -lines of commands and program output but none of this -will be interpreted by rc shell. - -The interpretation of commands is supressed altogether -when ESC is pressed to put the window in hold mode. -The window border and text will change to dark blue to -indicate the hold mode is active. In this mode you can -type multiple lines of commands and edit them. -Pressing ESC again will release the hold and send the -lines of text to the rc command interpreter. - -The DEL key sends an 'interrupt' note to all processes -in the window's process group. The usual intent is to -terminate the execution of the current command. It is -also a convenient short cut for ensuring you have a -fresh command prompt. - -FURTHER INFORMATION - -For further information, try the rio(1) manual page. -Type "man rio" or click on rio(1) in either of these -sentences and select plumb from the button 2 menu. - |
