| 22 | .SH DESCRIPTION |
| 23 | .I Proof |
| 24 | reads |
| 25 | .IR troff (1) |
| 26 | intermediate language from |
| 27 | .I file |
| 28 | or standard input |
| 29 | and simulates the resulting pages on the screen. |
| 30 | .PP |
| 31 | After a page of text is displayed, |
| 32 | .I proof |
| 33 | pauses for a command from the keyboard. |
| 34 | The typed commands are: |
| 35 | .TP \w'newline\ \ \ 'u |
| 36 | newline |
| 37 | Go on to next page of text. |
| 38 | .TP |
| 39 | .B - |
| 40 | Go back to the previous page. |
| 41 | .TP |
| 42 | .B q |
| 43 | Quit. |
| 44 | .TP |
| 45 | .BI p n |
| 46 | Print page |
| 47 | .IR n . |
| 48 | An out-of-bounds page number means the end nearer to that number; |
| 49 | a missing number means the current page; |
| 50 | a signed number means an offset to the current page. |
| 51 | .TP |
| 52 | .I n |
| 53 | Same as |
| 54 | .BI p n\f1. |
| 55 | .TP |
| 56 | .B c |
| 57 | Clear the screen, then wait for another command. |
| 58 | .TP |
| 59 | .BI m mag |
| 60 | Change the magnification at which the output is printed. |
| 61 | Normally it is printed with magnification .9; |
| 62 | .IR mag "=.5" |
| 63 | shrinks it to half size; |
| 64 | .IR mag "=2" |
| 65 | doubles the size. |
| 66 | .TP |
| 67 | .BI x val |
| 68 | Move everything |
| 69 | .I val |
| 70 | screen pixels to the right (left, if |
| 71 | .I val |
| 72 | is negative). |
| 73 | .TP |
| 74 | .BI y val |
| 75 | Move everything |
| 76 | .I val |
| 77 | screen pixels down (up, if |
| 78 | .I val |
| 79 | is negative). |
| 80 | .TP |
| 81 | .BI / nview |
| 82 | Split the window into |
| 83 | .I nview |
| 84 | pieces. The current page goes into the rightmost, bottommost piece, |
| 85 | and previous pages are shown in the other pieces. |
| 86 | .TP |
| 87 | .BI "-F " dir |
| 88 | Use |
| 89 | .I dir |
| 90 | for fonts instead of |
| 91 | .BR /lib/font/bit . |
| 92 | .TP |
| 93 | .B d |
| 94 | Toggle the debug flag. |
| 95 | .PD |
| 96 | .PP |
| 97 | These commands are also available, under slightly different form, |
| 98 | from a menu on button 3. The |
| 99 | .B pan |
| 100 | menu item allows arbitrary positioning of the page: |
| 101 | after selecting |
| 102 | .BR pan , |
| 103 | press the mouse button again and hold it down while moving |
| 104 | the page to the desired location. The page will be redisplayed |
| 105 | in its entirety when the button is released. |
| 106 | Mouse button 1 also pans, without the need for selecting from a menu. |
| 107 | .PP |
| 108 | The |
| 109 | .BR m , |
| 110 | .BR x , |
| 111 | .BR y , |
| 112 | .BR F , |
| 113 | .BR / , |
| 114 | and |
| 115 | .B d |
| 116 | commands are also available as command line options. |
